So I've been surfing alot recently and have been working on perfecting some of my tricks. Recently I've been noticing that when I go to spray or snap or cutback my board will follow... but not as easily as I would like it to. Now this may be because I ride a 5'8" 19.25" 2.25" board which is a bit on the wide/thick side of things and whenever I borrow some of my friends boards which may only be 18.5" I feel like it will turn alot more quickly and easily. So now it brings me to the question should I invest in higher quality fins? Considering I'm still riding the blank white FCS fins I got when I bought my board. Will it make a noticible difference? Which ones should I get? Keep in mind I'm only 125 lbs. and I know that there are weight suggestions when it comes to sizes of the fins. Thanks!
