Ok so I got the Pintech 10" TC in the mail from guitarcenter.com.
First impression: Damn this thing feels light! Before I opened it up, I thought they might have sent me an empty box. It's muuuuch much lighter than the Roland CY-8.
However, don't take that to mean it's flimsy, because it's not. It's a pretty solid plastic disc, just like the Ion cymbals are. I tried bending it like in that video posted earlier and could not. It has a wedge of what feels like gum or foam rubber on the striking side covering around 1/3 of the disc, also like the Ion cymbals.
So then I reconfigured all my cymbals so my Ions were now blue/green and the Pintech was set up as the hi-hat. I actually mounted the Pintech on one of the stands that came with the Ion (after removing the saddle bit to use on another stand) and used my extra boom arm to mount the 2nd Ion. Here's a few pics:
Now how can I say this without using too many expletives...this thing is FREAKING awesome!! It's MUCH quieter than the Ion and even the Roland cymbals and it responded perfectly to everything I could throw at it. Edge hits, bow hits, 16th notes, all spotless. I didn't even have to slam it hard to get sparks on the screen during freeform sections.
The only possible bad thing I could say about this is that the rebound off their foam or rubber or whatever that coating is could be better. It's plenty quiet, but not so great for rebound...I'd rate its rebound right around the same as the RB2 drum pads.
I'll make a vid or two of it this weekend, but for now take my word here: If you're looking for a 3rd/4th/8th (or replacement or whatever) cymbal for your Ion kit, get this! I bought the 10" for only $36.51, and I'm sure the other sizes (14" - $39.20, 16" - $47.20, 18" - $55.20) will work every bit as well as this one does.
01/09/09 EDIT: Because Hope Drums has been so amazing, I have now decided to promote them as the sole source of these cymbals (barring the one exception below). Until Brian tells me otherwise, always assume they are in-stock here, and they DO ship internationally:
Hope Drums also has a few special bundles put together especially for Rock Band that include cymbal, mount, clamp, cable...everything you need to attach this thing to your Ion kit and get to rockin'.
WWBW (seems to be one of the best for shipping prices to Canada):
