Depends on the boating you want to do. I don't ski or any of that, and prefer alum. It really isn't that choppy. Delaware is nice only in the fact it is 2 miles from the shop and is always quiet and open for any testing.
Not a fan of lake erie, if I am going to be driving that far might as well go another 3 hours to cumberland. Also don't like griggs or oshaughnessey, the length limits and speed limits kinda throw everything off. Their probably not bad places to ski though.
