^^^ If the work, great. And when they fail you're done for day. Well, unless a shop stocks parts or the whole roller assembly for your bow. Martin had the TRG/SOS and it was junk to start with and made to fit all bows (another mistake). And really messed with making the bows with guide rod holes off to the side of the riser, effecting making them junk for adapting to another cable system. Hear comes Mathews with their roller guard. Man comes to the shop and I don't have Mathews bows or the parts to fix his roller guard. He finally got a Mathews dealer and the dealer robbed a new bow of parts to fix the roller guard.
Athens (?) came up with their roller guard system in 2011 or coming out for 2012 (see pic). Saw this new out at the Vortec Open. I wasn't all that thrilled. So long ago I can't remember if it was for one model or to fit all.
You have to remember many bow companies have tried many different cable routings (covering all), but then the problem stems from short ata bows, cam lean or rather excessive cam lean at full draw. Long ata bows don't suffer near as bad.

There was Tilt Tamer (out in 2011-2012 Lancaster catalog) and the Arc-Tec (out in 2015-2016 Lancaster catalog - standard model and PSE model). Again both gone. Something ancient worked, the old style aluminum guide rods. They flexed. I rob every old bow that had these and sold them across the U.S. for more than what we could get for the old bows. Martin Staff shooter tried one on his newest Martin, a Onza 3. Just removed the TRG/SOS and installed the old aluminum guide rod. Draw weight dropped instantly and amazingly the bow was faster by 7 fps.
Another fix that worked came forward from a youngish Martin shooter. He took a stainless steel rod and bent it to mimic the Tilt Tamer.
Basically, we shooters have been doing the testing to prove out all these cable guard systems.
Set screws held the TRG/SOS in deep groove for it . Pretty sure it was Athens and it's one size fits all roller guard.
