Have the Glide Pro rear isolators/front mount on my '91 FLHS and it works great. Am trading that for a "new" 2007 RK and have boiled down my stabilizer options to either the Sta-bo isolators ( same as Glide Pro and waaaaaay less $$) or the Progressive Suspension Link as I don't like the idea of all that shat hanging under the bike. Just my .02 cents and a well reasoned conclusion IMHO. :-)
