Question about aero position/ bike fit

I'll try to keep this as short as possible, but some background info is necessary for my question to make sense.

Last year, my first in tri, I rode a Trek 1000 with aero bars. This year I upgraded to a Felt S25 tri bike and took the aero bars off the Trek--still train on the Trek some and use it in group rides with roadies. Both bikes were bought at a LBS, but fitted by different people. The seat on the tri bike was always a little higher (about 1 1/2 inches) than the one on the road bike and I was never as comfortable on the higher seat. Not knowing whether Felt seat was too high or the Trek seat too low and I was just used to it, I re-checked both (heel on pedal, leg fully extended), and in fact, the tri bike seat seemed a little high. I lowered it this weekend and rode the tri bike this am--much more comfortable. The only thing I noticed different is that now, when I'm in the aero position, the tops of my thighs just barely touch the lower part of my abdomen on the upstroke--I'm not overweight and I don't have huge thighs (6'1, 170#). Is this ok, or should I not feel this and get "re-fit" at the LBS? I'm about due for the dial-in on the new bike, so now's the time for me to ask.

Thanks in advance.
