Al, i just got a 08 lsv with the gravity 3, how long does it take to fill/empty that 750lb bag? in looking at the pictures is that another fill or empty port in the front of the bag? if it takes a long time im wondering if you could get a portable tsunami pump to help speed it up--this is one of the familys biggest gripes about me surfing is the time to fill and empty.

thanks

stacy
