Any Cobra from the last few years along with the Ping G30 or G. Cobra and Ping have the easiest adjustable hosels. Cobra's can be adjusted from 9-12 degrees (the non + models). If you want at least 12 degrees the Ping G30 and G come in a 12 degree model. You can adjust up to 13 and down to 11 degrees with .6 degrees in between.
If you're looking for a higher trajectory I'd recommend the Ping's. The Ping's are the most forgiving driver on the market followed by Cobra. Can't go wrong with either. I have the G30 in 12 degrees and the Cobra Amp Cell, Bio Cell and F7. The Cobra Bio Cell, F6 and F7 use the same tip adapter, so you can inter change shafts in you want. Although the Bio Cell and F7 use a different size wrench.
