+1 to BLZ2DWL
In earlier days, before I found Speedzilla, I got the FBF risers for my SS, and, while the change in angle made a big difference, I wish I had more room to adjust. To do over, I would probably chunk the change for the CC risers, and be nice to my wrists... in fact maybe I will, wanna buy some FBF risers?
Seriously, the rubber damping on the ones you posted sounds good, but the lack of angle adjust is a minus, and I would be concerned about them becoming "loose" (in the rubber).
(may be less in other countries)
