Pistol grip is awesome if you have a handle long enough so you don't have to adjust your whole body for every up shift. Checkout MGW's knobs (and shifter..I like it a lot more than the pro5.0), they make some trick pieces with cool logos! www.mgwltd.com
I've got the old MGW "Blue Handle" race shifter. You can get pretty much the same type shifter with the Orange Handle they make now, and you can call them and ask for the Silver Handle which would basically give you the shifts of the old Blue Handle.
