re: Looking to get a new driver.

I’ve been looking at their website, but I don’t know what shaft or loft I should get. I have 2011 Nike straight driver. I’ve increased my swing speed since I’ve taken lessons and worked some things out and started to balloon my shots off the tee. I usually hit it about 210 but it goes a freakin mile in the air and has no roll out. I’ve talked to some people and think I need a stiffer shaft. That’s why I haven’t pulled the trigger on a new driver yet.
