I ride Elka's as well as my My friend Mike Troiano (NEATV PRO). we both loved the elkas and they are easy to adjust but it does take time to get them dialed in like any shock.
The front shocks are flawless, but as mike troiano saw this year, the faster you get the more often the rear shock needs to be rebuilt. Mike was having Donald at BCS performance rebuild his shock atleast every other race, if not every race.
I had to have my rear serviced 3 times in 12 races, and i only ride at races...
I had Fox's on my LTR's a few years ago and liked them. Either shock is comparable IMO
