I too, am a devotee of using flies with spinning gear. I love the slow fall, (sink rate) of a wet fly presentation made with a fly rod, but don't usually have room for a backcast.
I've been experimenting with popular wet fly patterns emulated on 1/80oz or 1/100oz jigheads with foam bodies. The weight allows for a decent cast without the need for a casting float, while the foam bodies slow the sink rate through the water column. Still looking for that killer combo for big BG's, but I am seeing very promising results.
