The issue is your poll doesn't cover all options. The subtext of the 5/4 is that it's great for Hawaii, but most here don't consider it to be ideal for Coz. The 3mm, OTOH, is great for Coz but too cool for repetitive diving in Hawaii.
I know, I just wasnt sure how to word a poll to cover all the options. I know it's impossible to get one wetsuit for all conditions, I just want to make the best decision considering the $ involved.
Thanks for the feedback.
