I sent Clearview an email and they said you could place a order and try it out on your bike. As long as you don't take the protected plastic off you can send it back for refund minus shipping or try a different height. Sounds like a good deal trying it out.
They also said with my height 6'2" they would recommend our 9.5" with the recurve. This would be for the 09 SG.

Again, I would mess around with some cardboard before actually ordering anything. Their return policy is very generous but their lead/delivery time was like 4 to 6 weeks I think when I ordered mine so you don't want to waste several months messing around. Get it right the first time and enjoy it quicker!
