I also ordered from epmperf.com.
I've been using the Hyperpro since June this year on my 2012 GS.
I had a Scotts on my Triumph Street Triple which I sold along with the bike. Had I found the Gorzilla mount maybe I'd have kept it, but I like the uncluttered install of the Hyperpro. I also found I never adjusted the Scotts much, it was set and forget, so location wasn't much of a factor going with the Hyperpro mounted out of reach on my GS. If I was doing a lot of off road riding maybe I'd think twice about the location.
The Hyperpro got rid of the squirley front end. Love it.
If I was to choose between the RM style mount and the Scotts with that Gorzilla mount, it would be the Scotts all the way. The RM and GPR mount under bar risers, and from what I've read, interact with the stearing stem
, however I'd get Scotts Performance feedback on that mount first. There's got to be a reason Scotts isn't making a mount kit themselves for the R1200GS, I'd want their blessing. Just my 2 cents on the topic...
