Originally posted by Matt Green: No one has mentioned whether you get a helical or straight or clamp or rt or left. Personal preference and either is OK but will be a question when you get your bitz (or other). you can search the forum about pos/neg for rt/left and lots of opinions on helical vs. straight. Probably will evenuatlly want both straight and helical for 'experimenting'. Good luck - as others have stated 'tis funmgreen
