Yes it's the Indian...but the Indian doesn't have to shoot with a crappy bow, just because he's good enough to beat anyone with it. If the CueTech didn't shoot/feel as good or better to him than his Mom's old Schon R series cue, he'd still be using that one...but apparently his buddy's old CueTech felt good to him, and he's tinkered with the ferrel, tip and extension to perfect it, so that's what he's sticking with. Some of the best hitting cues I've ever tried cost less than $200.
Earl put Mike Gulyassy through hell to perfect his "javelin", and he loves it (told me so the one time I met him)...Shane started with something off the shelf and got there himself. Most production companies have figured out how to make a pretty darn good baseline cue and perfected their process...nothing wrong with them, and with a few modifications it will play perfect for you, a custom maker would have to kill himself to replicate the process, since he's starting from scratch and maybe not the same place.
