Just got a a 16 lb Blue Hot and yes, although its core design is not very far from a 3 piece pancake core, it is different and it responds very differently.
I drilled mine almost leverage, 4x4, with 1/2 oz side weight to try to induce a little more drive in the ball as it is so even in its reaction. I was lucky enough to get what for this ball is a huge pin out of almost 2.5". Tried it on a house shot and it moved pins better than average.
As far as the Barrage is concerned, look carefully at the core design on Dyno-Thane's own webpage. The huge bottom piece, below the obvious chuck at the top, is just slightly shaded, indicating a mass than is denser than the rest of the shell. I don't believe this is a plain pancke core.
