I'm in the same boat man.
3-trinity slim's
2-Jasper 16mb
1-opus (but who gives a crap about this one really?)
All 6 run perfect on coolrunner-II based eBay boards, matrix glitcher, and have not tried the "glitch-board" cause I dont trust the company.
However none of these will do anything short of a good boot once out of 50 if im lucky on the tx coolrunner. I've been an avid tx fanboy since the original release of the x3 on the old school xbox, and I have been lucky enough to run every single release after that except the cki and the jungle-flasher edition of the usbpro.
In that I just absolutely stand by tx and their products, I hate to see that a product as awesome as the coolrunner has such a lack in updates for the timing files. Now I do understand that every console is a little different from the last one, but the ability to customize your boot timings on the matrix offering is leaving the coolrunner behind substantially.
Again I back tx 110%, but with the announcement of the Demon coming soon, it's hard to imagine that they are going to continue to push the coolrunner timing files to the front of their research capability. I just hope (and I know i'm not alone if you guys are by chance listening), that if it is a dual nand offering, it will compile everything the market has learned from the coolrunner.
-Offer the adjustable pcb for slims right out of the gate
-make the ability to program the chip via usb or even the nand to coolrunner cable [From outside the console]
-Offer the ability to run a standalone timing file, or adjust it to suit each boxes needs
-look into the possibility of running a glitch board update within the dash [Thinking along the lines of an xex that will update the glitch board for us if this would even be possible.
Definitely with the OP on his ideas though. Again I hoep they are listening, because we as end users, need the ability to build a customized glitch timing for each console.
