I just got the TvC stick and it is pretty solid out the gate. Number one thing that stuck out was the construction of it. Love the matte face and the weight of the stick. I wouldn't say it's significantly heavier than the PS3/360 SE, but there's a noticeable difference. Buttons have a nice soft touch and are much better than its predecessor. And granted the stick is no JLF or LS-32, its leaps and bounds beyond the PS3/360 SE.
I rocked some CGoH awhile ago and all my inputs felt crisp. I'm like haunts in the fact that I'd rather have my parts custom, especially since I'm a big Seimitsu fan. Aside from that fact, this thing feels all sorts of good. We'll see how well this holds up after constant usage, but as of now, this is obviously the best stock stick out on the market for the Wii.
