Been doing triathlons for about three years and am looking to upgrade from my 2015 TYR Category 1 wetsuit for future 70.3s and possibly an Ironman within the next year. I loved the buoyancy of the TYR but found the shoulder mobility a bit too restrictive. I'm an adult onset swimmer in my early 50's with minor shoulder issues and a 39:20 HIM swim at Mont-Tremblant. I'm considering wetsuits in the $500 range with the Roka Elite and Blueseventy Reaction being prime candidates. The Elite has a buoyancy profile of a 1:3:5 and the Reaction has a 4:5:4. Does this mean that the Reaction is more buoyant? Both claim to put the swimmer in the "downhill" position. Are these the types of buoyancy profiles a swimmer of my ability should be looking for or would a suit like the Orca 3.8 with 5 mm from top to bottom be a better match? I'm looking for a recommendation to which suit would provide better buoyancy with good shoulder flexibility while allowing me to gradually improve as a swimmer. I fear the 3.8, while providing me the confidence-inducing buoyancy in the open water that I'm looking for, would ultimately stunt my growth as a swimmer. Are there other wetsuits in the $500 range that I should be considering? Thanks for your thoughts.
