Tinker And here we have come full circle. 🙂 There are plenty of component clubs that you can get with this description. In fact, you can have one hand-picked to these exact specs! You just can't achieve this with an adjustable hosel (i.e., the "advancement" that has supposedly left the component industry in the dust and that is making them obsolete until they embrace it!). So, your original post has asked that component companies produce the very thing that runs counter to what you actually want/need. 🙂
P.S. I have an 11* SMT (insert BANG, Geek, etc.) that is 1 degree open. Want it? $200. LOL!
P.P.S. After posting this, I went to have a shower and realized that you actual may be able to achieve your specs with an adjustable driver. Buy one with a 12 degree loft and then adjust it to 11 degrees. That may achieve it. However, "may" is the operative word here, and the certainty won't be like a hand-pick. My point, again, though is, if you know you want that spec and that is the right spec for you, why do you want/need adjustability?
