Herman, do you own or have you used an Excelerator? You're the one who always says. Try it and see. Well, buy one, try it and see. Sure some are having issues but many are not. I have never had any major issues with the Liquidator or the clips, ever, from day one. The Excelerator, although by no means perfect, is a much better handle than any of the Wagtails, standard or modded, I have used. Close out initially was a minor challenge but a small change in technique sorts it. I can't speak for the High Flyer as Wagtail and I parted ways prior to Precision Glide, but as nothing has changed with handle or pivot I can't imagine it will be very different. The Excelerator pivot is smoother, more direct, and because situated closer to the channel is very very quick. I have huge respect for Ryu and his talents but as clever and tidy as this is it cannot be called a FIX because the design features that are an integral part of the overall design have been removed. Also this in no way addresses the problem of even pressure on channel ends that you say your design has sorted.
