Have any of you relocated the ski locker fat sac vents from the REAR of the bag to the front of bag? Once there is enough water in the bag is covers your vent hole and you end up with a bunch of air that cant get out so the bags never completely fill. I was thinking of cutting a few of these zip ties and venting the bag off the fitting at the front of the bag instead of the rear. Whats the consensus here? Cheers
