Not much experience at Spinny but when I went with some buddies we just waded out to waist deep and were able to land a few.
Wind blows from 1100 am til darn near dark(what I have been told). I would not find it to be much fun in a tube fighting the wind, but that is me. FYI, I do not have much experience in a tube.
Did not fish 11 mile but was told that you can get into pike from shore(april time frame). Don't know if that changes with the change of seasons.
I am sure someone on here can be more help than I, but you know as much as I do now about those two res's.
