Hmmmm... that all sounds like great logic...
I've just never experienced any of the drawbacks you cite. When my lure is in its last few inches before hitting the water, my right-hand index finger is already putting the brakes on the line to drop the bait in the exact spot I want, and my left hand is in motion to engage the reel. It's just a timing sequence like any other, and I've got those casts down to nearly pinpoint accuracy. I'm not waiting to engage the reel - it's engaged simultaneously with the lure breaking the surface of the water.
As far as heavy line, I've been using 12 lb flouro on that spinning reel for the last couple years, and I haven't broke anything off yet. My baitcasters are loaded with 40lb braid.
I think it may be a difference in typical conditions (cover types), and size of fish. We're fishing cabbage, pencil-reeds, docks, rocks, ledges, and deadfall. A 20-23 inch bass (5-7 lbs) in these parts is frikkin huge. The biggest most people catch on a good day is 19" to 21". I know they get a helluva lot bigger in your neck o the woods. But I haven't found a need for anything heavier than 12lb test for the cover/size of fish.
Or, I could just be too much of a puss to man-up and use a baitcaster for all my bass-fishing needs.
