Approaching the wall to do flipturns [a momentum problem]

So my 100 free SC time now is 1:01.5 approximately. I'm basing that off of my latest 100 free swim, which was LCM, but I used that swimmingworld conversation calculator which gave me the above figure. Last week, my coach had me do a timed 100 free off the wall at the end of practice. I clocked in at 1:02.5! So I'm very happy about all that. I am having a slight problem though. As my technique improves and I get faster at actually swimming, I'm finding my flipturns are having a problem adjusting. When I do a set on like 90% or higher, and I flip around at the wall, it's like the momentum my body had established coming into the wall throws me off and I spend an eternity with my feet practically pasted to the wall while I get my balance back. In reality, the total amount of time wasted is probably only half a second at most, but you know, you guys are swimmers, you understand... that's an eternity in swimming! It's very frustrating when for the first 25 or 50 of a set, I can keep pace with some of the fastest people on my team, and then I get to the wall and I'm smeared, left floundering, while those fastest people just pinball right off. And this isn't an old problem... I have now been doing flipturns for over a year with no problem, but now they've become a problem (an opportunity?). How do I accomplish a crisp, rapid flipturn without sacrificing any of my speed built going into the wall? Or is this just a sad fact of swimming I'm banging my head against... that all swimmers have to slow down just a tad before flipping? I don't wanna slow down! :( I have a SC meet in a week. I'd like to fix this before then. What do you guys think?
