I've got a bedded in set of RS14's available if you're interested.
I find the RS29 much too hard a pad, there mainly used as an endurance pad so they are long lasting but don't have the bite and feel and they're harder on disks.
If you're running Alcon brakes, you can use either 17mm or 20mm - they are designed to accept 20mm which will last a bit longer! I think the AP brakes are the same, but best check by measuring the gap between the disc and inside calliper pad housing or call the factory to confirm?
