I am a 17HC and just purchased an i20 / 10.5 loft with a project x 6.0 shaft.   Swing speed for me is 88 - 93.   I have trouble getting any ball height with any driver.  With the i20 I had improved ball flight and increased drive distance by 30 yards over my R11.   If it looks good at address, feels good when you hit it and you like the results...buy it.
