Board Size

Hello all. I plan on getting a new board shaped for myself soon. I live on the East coast and don’t really surf in the winter, so most of my surfing is done in mushy, summertime waves. However, there are always those bigger days that I find myself not properly equipped for. I’d like to remedy that with this new board. I stand 6’3 and weigh about 200 lbs, and have been surfing for 8 years or so. I’m 21 years old and I’m definitely not ripped, but i’m in good shape. I started on a really thick Canyon 6’6” back in the day, but have really fallen in love with my 9’6” noserider over the past few years. This summer I’m looking to get back on a short board. I’m just here to hear some opinions, I’m open to any and all advice! I’m definitely a good surfer, but don’t know everything there is to know about surfboards. Right length? Width? tail shape? rail shape? Like I said, I do most of my surfing in mushy east coast waves, and I’m 6’3” 200lbs and in good shape. I would appreciate any advice you could offer! Thanks a lot!
