So, I bought a demo Jitsu 5.5 this winter. The comfort/outfitting is great, however, I'm discovering the boat is slow. I am female, 5'5", 133 lbs. I was frustrated with the boat during high water; had trouble getting it over "fences" to catch a wave. Who else has experienced this w/ the smallest Jitsu? Do you think I would like a Star better?
