My t-halls edge in the tail has become wiggly, asd through the base i can see a line forming about 1 cm in, tracing where the edge would be under the base? Is it only a metter of time? If you need pics i can try to get some up.

Sounds more like a seperated edge than a delam. That would mean that a lot of steps were done poorly in the construction of your ski because several things have to fail in order for that to happen. I'd ask about getting a warrantee; with how much you paid for those you should at least get a ski that's built ok.
