Fitted to a Sanwa JLF, this is one heavy handle. You'll need a 2lb or even 4lb spring. It has a good grip, nice texture, no moulding lines and looks amazing.
Very comfortable over long play sessions as long as it suits your stick and playstyle. If you use an oversize actuator, probably go for the strongest spring you feel comfortable with. I love it, but it may not be for everyone.
