260 on a bass mid will break and ive seen more than a few.
watched a good friend dive for his new sporty after one weekend on the lake .....never found it....
if your real easy it might last a while but who is easy on a 260 with a lead flip flop? 350 hp fugetaboutit!
if you are that serious that 20lbs is a factor then 15" ros or drag mid is the way to go, otherwise the 280 os mid is what i would use with
pump in the boat vs 3ram bass is not a big deal .
