Surfing Waves

Been riding a foamie for a while, 2 summers ago started using my buddies 6'10 hybrid. Super fun board just a little hard to paddle in on the shitty days sometimes, looking for something to catch more waves so i can progress faster, and something shorter i can whip around. Really looking into a fish board so i can ride the decent days and the shitty white wash ones, I am 6'3 and in the ball park of 200lbs. I was looking into a 6'6 ronjon quad fish, found a great deal on a brand new one on craigslist but not sure if its gonna be to big of a board to whip around. Wondering what are opinions on the kind of board I should look for and sizing to be able to catch a lot of waves even on those crappy days but still have decent control to progress and throw around on a decent day. Thanks.

Should be good. You don't want to go too small on your first board, you want to catch waves and get better. Eventually you will become a better surfer and will need a smaller board, so this would become your small wave or mushy big high tide board and you will get a smaller one for walled days. Besides, for a beginner a bigger board means more waves, thus more fun, a smaller board means less waves and more frustrations
