It would be quite exciting to see some new C/L releases from Sig. I would likely buy any new .15 to .60 size control line kit that Sig would care to produce. There is nothing at all wrong with the current offerings, it would just be nice to see some new stuff, anything C/L. I did pick up a new Banshee kit at the contest this past weekend. I didn't need one, I bought it "just 'cuz". I do plan to build it, not just keep it on the shelf.
On a separate note, here's something else to consider. I'm not a big ARF fan, but I would think that both the Twister and the Super Chipmunk would be excellent candidates for ARF's, or even ARC's. Heck, maybe even the Fazer as a C/L ARF? It would also be great to see the Primary Force available again.
