I never had the wobble, but I bought Steve's setup anyway, super quality, especially the counterweight for the 11, and especially the 15'. I went with the smaller counter-weight and am super happy. I'm going to sew some small pouches to replace the ziplock bags for the weights. So far, I love it. Top quality for sure. I just wish I knew colors were going to be available but nbd, I have the entire setup including shafts for all 3 coils. I couldn't be happier. My one "gripe", and it's a *minor* gripe, is that I wish the lower shaft had some demarcations so it would be easier to setup out of the trunk. For now, I use a silver fine tip sharpie, but having 1/4" demarcations on the lower would be awesome. Now, to get together with him to do the same for the T2 / F75!
