I have an old m10 hog fish currently its a 6'0" I do fine with it I'm actually progressing rather quickly. I'm 5'8" and 175 also I want another 6'0" I am just curious on the differences in the tails and fins, because i haven't got to ride anything other than a swallow tail with a thruster. The m10 is beat it was a freebe last year someone gave it to me it was bucckled and missing two fins, I'm grateful if needed so much work though because i did learn a lot about fixing them myself quickly
