Re: how much better is this?
For drilling the chain tensioner in place I found a very good alternative. Replace the mounting hardware with better nuts and bolts. Get an old inner tube and cut to size where you will mount. Put on the inner tube cutting and then mount your tensioner with the new nuts and bolts, then tighten the heck out of it. This thing is solid. I put it on and then realized it was a little bit off so I tried to kick it into place. It turns out I had to KICK the S(bad word) out of it just to make it budge. Works for me. Might be bad down the line as the rubber wears out, but thats why your checking your bike all the time right?
