Dude stop worrying so much. The golf bag works for sure. I travel a lot and have never been charged. If your that worried throw a few cheap golf clubs on top of the gear.
Yeah my twin tip straps board is 131. When converting to boots i went with the 140 custom. I love the switch. I was surprised how much more pop the bigger board gives me and the landings are sooo much better. I weigh 150 pounds btw.
