blue seventy

I know this has been answered a million times, but I can't keep track of the numerous Tech Suit threads and I confess to being confused about the "pre-2007 suit" exemption, yadda yadda yadda... So for the men we are going to be allowed jammers, even if the shoulder-to-ankle suits were legal pre-2007?

It's not much (no pricing yet, and only small pictures), but in case anybody didn't see it B70 has a page with some additional about the new suits: www.blueseventy.com/nerotx I wonder how much slower these suits will be, if at all, for women? It sounds like the new suits will still offer compression and significantly reduced drag. I suppose no one knows for sure but the new suits should be slower than existing B70s, even for women because: - permeable fabric should prevent trapping of air against skin, eliminating flotation - "textile" fabric may have higher drag than rubber-coated fabric - less coverage of skin due to knee length maximum - elimination of zipper could reduce coverage to allow the suit to be put on without a zipper

I am sure they will be slower. However: -- permeable material can certainly still trap air if it is hydrophobic enough (I have grabbed a hydrophobic filter in lab by mistake and tried in vain to force water thru it; it doesn't work even though the filter is porous). I suspect buoyancy (density) of the material was a bigger reason for flotation of the previous suits; I've always thought the air trapping thing was a red herring. Even practice suits will trap some air. -- maybe, though I hesitate to put limits on the abilities of material scientists and suit manufacturers to innovate. -- I definitely think coverage is maybe the most important factor of the new rules for men. But how significant is coverage of shins/calves? Some but not (say) 5%. It is just one datapoint but in a trials/finals format last summer I fast just as fast in jammers as in legskins; at the very least this implies (for me anyway) that the extra coverage is not a huge factor. -- less compression without the zipper; another important factor. For women, my gut feeling is that (a) loss of buoyancy of the material and (b) less compression will be the most important factors. Just my :2cents: I frankly think durability will be the biggest factor... I think on the women's side, at least, these suits will still be plenty fast.

FINA rules apply to meters only. USMS is the only organization that conducts competition in yards. At the convention, we had a hot debate and a close vote on what to do about yards. Everyone agreed to follow FINA's recommendation on meter meets immediately. We debated whether to allow suits through SC Nationals or ban them at the same time as FINA. Because the SC season had just begun, a close vote recommended that we ban suits for yards at the same time. At that time, we expected a decision by the end of Sept. Now that we are so far into SCY season, I honestly don't know what the Rules committee will recommend. Somewhere on the Forum (in this thread?) there is a statement from Rules that tech suits are allowed for the Hour Swim through all of January. I am prepared mentally to change suits whenever the ruling states. I'm not, however, prepared with a substitute suit. I have a B70 and a TYR Tracer Lite, but the TYR is also ankle length.

I frankly think durability will be the biggest factor... I think on the women's side, at least, these suits will still be plenty fast. Nope, I agree with Chris on this one. Less coverage, no zipper, less compression, no float = slower. Period.

Even practice suits will trap some air. I disagree,the impermeable suits trapped air in a way that was very effective and will be difficult for a permeable suit to duplicate.

While I think taking suits back to 1999 styles cuts is a dumb idea, if FINA does ban the bodysuits for us, then it should go into place immediately for all courses. People are saying "what about those that have swam scy meets in the suits while some of us haven't done" Well, the larger majority of people that haven't still have 4-5 months before their major scy meets(the zone meets and nationals) So, we have plenty of time to make adjustments in mental take and phyiscal training. Granted, I think FINA should allow masters to keep their suits but it's not up to me

I disagree,the impermeable suits trapped air in a way that was very effective and will be difficult for a permeable suit to duplicate. I have aproblem with this ascertion. If the suits trapped air, then that would increase over all bouyancy but yet most swimmers were reporting being able to stay under water for longer, so much so that a lot of swimmers were reducing the number of SDKs being taken for fear of breaking the 15m mark. For me, I found that I was routinely surfacing at or slightly past the 15m mark on breaststroke starts and going past the 10m mark off turns with the B70 but being well short of those marks in my Fastskin. True some of that maybe the increased slide factor but I just don't buy the 'air trapping' arguement as an advantage. But then again, it's also :dedhorse::dedhorse:

But then again, it's also :dedhorse::dedhorse: You stay under further due to the increased slipperyness.The buoyancy is more noticeable on the surface(or if you get the dreaded bubble butt.) It's not:dedhorse: until the rules change for Masters.
