I'm using the Chopped Switchblade on my Speedmaster. There are a few threads with the part numbers on it floating around here to help put the whole package together. The Switchblade screen is wider and doesn't seem to buffet like the Triumph screen does. YMMV.
I picked up a set of lowers from Eddy. I'm not sure how much good they do, but I'm planning on experimenting with them more this fall.
