I've heard different things from different people. Most I speak to, about 95%, say that the Edge and TRS are not switchable without routing. BUT, I have spoke to maybe 2 or 3 people who have actually COMFIRMED replacing their TRS with a Lo-Pro and it working perfectly fine!! They said there was a huge limit to pull-up but that it did fit and was able to be strung up. Not sure whats up with that but I would look into it before buying a Lo-Pro unless you dont mind having to route if you have to. Like ripl3y said, if you dont mind shelling out a little $ to a pro then its not THAT big of a deal. Most should be able to do it no problem.
