When fishing Smallmouth it is fairly common to have a larger fish follow in and strike at a smaller one you playing to hand. In fact, I find it so common that I look for it and generally always recast to an area where one is caught several times to pick up the follower.

A couple of days ago I wish fishing a shalllow riffle, ripping a Gurgle Pop across and down and getting a hook-up very 2-3 casts. On hook up was a fish of no more than 3" ...I saw it clearly as it popped straight up about 10 feet from me when it whacked the fly...

The tiny Smallie and fly go back under, line goes slack, then a thump, bump and some considerably heavier resistance and another skyward fish...well, no trophy but the dink had given up it's place on the hook to a 10" Smallie!

I wish the trade up option was always in effect.
