Hi, I think the yellow Edge T.o. is a rare beauty.
First of all, you should give it a try to fix the head tube to be able to use it other than just a wall hanger.
A guy in Germany had same problem at this Alu Edge just on top of the head tube and fixed it with an homemade but nicely done Alu ring.

Personally I also think that the AMP fork isn't the optimum yet, alone using the one with the CroMo legs, at an Aluminum frame and polished rear end sounds not right.
Let me give it a try to convince you to keep on looking for another fork by showing a few old pictures

This one is from the Rocky Mountain Facebook site, showing it in use at a DH race.
And last but not least, not sure about the exact source of this picture, I think it was a recent article where someone made a visit at the RM HQ.
So even Rocky Mountain seem to have this frame still laying around.
