Brewer,
I used to use the X10 MTC 8-17# for all my fall king bobber fishin and land 30 to 35# hump kings like it was nothin with that rod,hard to beleive a 15# steelie would max out that rod.SH316 I would think that 10-20# float rod would be over kill for a spoon rod.That's the rod I use now for float fishin fall king's.Good luck,
