Here's a possibility:
You paid $X for the ZR40. So far, as I understand it, that's all you're out. They're sending you a T-hold to replace it, and at most online shops, the prices for both are pretty much the same. If you can sell the T-hold for enough to buy a new ZR40, you're not out of pocket any more than if nothing had happened in the first place. It's a hassle, but there's not much you can do about that now.
If the T-hold isn't going to do what you want and you don't think you're going to get enough use out of it to be worth your while, I'd get rid of it. There's not much point in having stuff you won't or can't use. If you kept the T-hold, you'd be left without that "sorta control ball for THS nights" reaction that you want and you'd end up buying another ball to go there.
You could sell the T-hold, get the Crisis Solid (or another ZR), and maybe pocket a few bucks for your trouble (almost certainly if you went with the Crisis).
