Never got any definite answers, but general consensus on this was:
Cover: similar to M80.
Core: Super Trooper core with higher total differential (or is it lower?) 0.050 vs 0.020
Reaction: similar to Columbia Action. Also reports that it was "a few" boards stronger than the Track Power Machine.
Overall a good benchmark ball.
All this only refers to the Columbia produced balls, not the Storm produced. Not sure if Storm ever produced the Full Tilt, but the Tilt was produced by Storm and Columbia - different core and cover.
