Curious why the STw² in 10* has a .5* open face angle since it’s weighted to produce a draw bias.
I would think face angle would be square or closed to help enhance the draw (or suppress a fade)
Good question. The STw2 was designed to appeal to a wide range of players. Understand, that if we made the face angle .5 degree closed, you would eliminate a lot of players from even giving it a try. It is slightly draw biased in weight, but that in itself should not eliminate mid to lower handicap players from trying it if they like the look. A closed face angle will. Face angle has a lot to do with how a driver looks at address. Also, there is an optical illusion in that .5 open looks square and square looks a little closed. In the old days we would make wood woods up to 1 degree open to make them look square at address. Same goes for metal woods.
All that being said, the STw2 was not designed to be that “anti-slice” driver. If we intended it to be that, we would have designed it with at least a 1 degree closed face, a lot more heel and rearward biased weighting and maybe even a little offset. We did that years ago with a CER driver. Maybe we need to do one again. I do think those that are looking for a draw bias club can still have success with the STw2 even with the measured face angle on the 10 deg. model being .5 degree open. If their shot is a consistent 30 yard+ slice and not willing to take lessons to help correct, they need to look at a closed face, heel biased weighted, possibly offset driver. Or, if they are Right Handed, aim further left…

Most excellent. Thank you…
