For float, I agree with the long-rod crowd and in my weirdness, I got a Michigan-style handle which is basically like a fly rod setup with the reel close to the butt-end and the long grip above the reel. This puts the balance close to the end, so holding it high is comfortable and gives you a little more height.
While extending the drift for hardware and drift rigs is easier with a casting reel, I still think for float, a spin presents better with the open bail because even with a freespool on a casting, it adds drag. I just use my free hand a la fly fishing when setting the hook...just grab the line and pull while simultaneously flipping the rod tip. I then just let the fish pull the line through my hand while moving to the bail and flip it closed to engage drag.
But like I said, I'm weird
