Speedo fastskin brief

Ok, I know I'm always complaining about the guys who wear these expensive suits. When I buy my own suits, I rarely spend more than $15.... But anyway, I got this suit as a Christmas gift: www.speedousa.com/.../ I'm assuming this should be treated like any other fastskin, and I shouldn't wear it for normal workouts? Just for meets, and maybe try it out ahead of time? Will I notice any difference in times between wearing a regular suit and this? I did try it on, it is my normal size, but feels tighter, but it still fits. Strangely, there is no liner in front like normal suits have. I haven't done a meet for 4-5 years, but I think this will help push me into doing at least 1 in 2008. Appreciate any thoughts. Thanks.
