Looking to fill my gap, I have a 510 dom and a 603 flexfire. Surfing east coast beach breaks would a custom alt 600 19.25x2.5 or 510 lost sub scorcher be the ticket. We get alot of days when it barrels and kinda steep but not quite enough for the flexfire. I love boards that feel skatey off my back foot. I have surfed a friends 6'2 alt before had the feel that I like off the tail but was a little to big for what i want the board for. Just wonder if making a shorter fatter alt would be what i need to make a semi grovel/chest to head barrel rider. I have never surfed the sub so not sure how it would fit into what iam looking for, let me know what you guys think, Thanks
