In Protero's catalog it says that they are coming out with a 24 cubic feet collection system that would fit basically all the models that the 18 cu. ft. system would. Would a hopper that big be a good idea or would it be too big and heavy? My thinking is larger size equals more efficiency. I emailed Protero about when the system would be coming out and they don't know because there hasn't been many people interesting about it and/or that don't know about it. I was interested in getting one for my Gravely 260Z. What are your thoughts on a larger capacity collection system for ZTR's, a good idea or not?
