Full Sleeve of Sleeveless Wetsuit for IMFL?

I received a new sleeveless wetsuit as a birthday gift 5 days before IMCDA in 2008. I swam in it once and was in love with the sleeveless. The water was nasty cold in 2008 and I still chose to wear it. It all comes down to personal preference. I really didn't notice much difference in buoyancy myself. I like the feeling of not being restricted in the shoulders and arms, and I never had a problem in the full. Had it not been given to me I likely would have never changed.

Get in the sleeveless and try it out to decide for yourself.

The jellyfish are the reason I bought the full in the first place, but I didn't see any at the Gulf Coast Tri so I started to wonder if a sleeveless might work.  I would bring the sleeved suit in case of a lot of jelly sightings for sure.  Mostly I am curious about arm fatigue from the full suit.

I've used full sleeved wetsuits (IMCDA) and sleevless (IMFL) and for Florida would recommend the sleeveless.  Less shoulder restriction, even compared to a high end full suit.  I got one little sting on my arm during Florida, so that was a non-issue to me.  Take them both though and try them during the days leading up to the race.  Then you'll have a better idea which one is "the one" for race day.  Good luck and have a great race.

2006 IMFL sleeveless 2008 IMFL with sleeves.  Water temp low 70s both years.  I like the sleeves.  I do not feel like the inhibit my shoulders in anyway.  Play with both of them and decide what works best for you. 

If you have a good quality wetsuit with sleeves I don't think it has much effect on your shoulders. I had a wetsuit with sleeves at IM FL last year and it made me feel more confident about jellyfish. Then again I have very limited ocean swimming experience so I was probably overly worried about jellyfish.
