For what it's worth, I just changed my rest from this rest to a drop away. The biggest complaint I have with the Catawba (and I assume it would be the same with the upgraded model) is that as the bottom brush begins to wear, and it will if you shoot alot, you have to compensate by lowering your sights. Once you replace this bottom brush, you have to again raise your sights to compensate for the new site and begin all over again. It's true, it does not damage your fletching and it really does not fall off of the brushes often enough to make it a deal breaker but the bottom brush seems to wear from arrow friction while the other two don't even touch your arrow, let alone wear. At first I thought this was a good thing, thinking as the bottom one wore, I could simply rotate it out with one of the sides. This works but as I said, you then have to readjust the sites again and start the process all over. I saw a new model out that looks like this rest but has some type of rubber pad or 'hard' rest on the bottom instead of a brush which looks like someone is trying to fix the problem. I have never used a WB for any extended time to see what brush wear does to the sighting but it's something to keep in mind when you are using these brush rests as opposed to a harder surfave.
