Been riding the 900 with the short fuse and 400 stab for a few months now. Prone board (4'7 and a 4'3), I'm 6'2" 170lbs. Really liking it but want to make it looser and better at turning. For those that have played around with the new stuff, what will give me the most bang for my buck?

ultra short fuse - $330
370 rear wing - $185
340 rear wing - $181

I live in Hawaii, so the waves usually have plenty of juice.

haha I'm getting a lil tired of throwing money into the sport. I realize the best option is the ultra short and a smaller stab, but I kind of only want to get 1 of the above for now. Which would you choose?
