Congratulations! Looking forward to hearing about your training and race experience.

Last year I raced in a wetsuit that Dex donated to me that felt pretty good in a couple of OWS practices about 5 weeks before my race, but then trained indoors the rest of the time. I put on about 8-10 pounds in the month before my race, and the suit seemed to restrict my breathing during my race. Of course, i may need a bit more experience with it to pinpoint the exact cause.

If you know in advance how your body reacts to the conditioning that you have planned, perhaps you can take that into account while shopping for a suit? I would guess that individual people might start and end up in different places with this.
