I posted this in the homeowner helper forum but did not get any responses. I'll try here. I have a Snapper 28" RER and want to get a bagger for it. The choice is: Flat single bag, or bigger capacity and bigger $$ for the double bag? I am leaning toward the double bag because I have a lot of leaves and I think it will save me too many stops to empty the bagger. My lawn is flat, no hills to deal with. Thanks.
