I have stuck with Zoots for my tri suits/shorts. I wore my Zoot ultras alone for Ironman with bodyglide and zero red spots (a first!). I did get a pair of Orcas because they are a bit longer and my delicate thighs can rub the inside seams with the zoots, but haven't tested them yet.

(I did have an LG top, but I have to avoid anything with zippers over sprint/oly distance or my neck is carved up by the zipper.)

Congrats on your race! The first is always a learning experience. An Olympic distance requires a fair amount of extra care vs. a sprint, but is still short enough to not feel like a test of your mental acuity at the same time You did very well.
