Got to try out my custom surf sac for the first time today. It is 30x30x30 and some where around 1100#'s. Fit perfect behind the driver seat and was a good wave but I want better. Any suggestion for a little bit longer? It is pleanty tall and I could get about 10' from the boat before I would lose it. Am I asking to much? '97 VLX 440 in bow, 750 in engine compartment, 440 on back bench seat, 1100 sac on floor and about 400 in the ski locker all on the surf side.
