sdandrea1 As far as COR etc, DCT the No Brainer & FS3 are all mfg to be at the legal limit. The 551 and Lil Bastard are both based on the DCT but mfg to be hotter than standard and not tested by the USGA.
As far as draw bias, heads can be hand picked but keep in mind the face specs are pretty tight. Almo used to order them mostly square to slightly open. Derek may have some slightly closed. Let me know what you may be interested in and Ill see if they can do it.
