I would get the larger size. You don't have to fill it all the way, but capacity is there if you need it. You will be able to go 2+ months with a 175# on one fill up. Nice not having to keep extra bags laying around to fill up every couple weeks.

I have a 175 and go thru 200#s a month with 2 ac BOW.
