I have the Grand slam and I like it. It is nice to be able to sit just about anywhere and it adjusts to how you like to sit. I prefer to kinda sit back a little so that's nice. Can be a little on the heavy side for long hikes, but the frame really doesn't weigh that much with or without. Most of their vests are on the heavier side of the market besides the Longspur. Very good quality and pockets are well laid out. My only complaint is that the seat was too soft for me, but I am also 215 pounds and like a stiffer seat. That's just my personal preference. Used it in the Black Hills last year and it was great.
