I have the 88ci 4500psi Stubby. This thing is a beast to carry around about mid day at the field. Yes it great that you dont have to go to the fill station maybe only once or twice durring the whole day of play. When I first got the tank I thought wow its the same length of a 68 just a bit thicker than a 68. It was light when it was empty. When they filled it. It was more along the lines of 3-4 pounds. If you like alot of air and less time at the fill station then a big tank is great. The consistancy of the reg is nice.
Its great if you dont mind the weight. I give it a 8 for the weight.
