Tibhar Aurus is a great suggestion. I think the speed is much less than MX-P though. However if you play, say, Mark V v.s. Tibhar Aurus side by side, you can tell that Tibhar Aurus does have some catapult effect so Tibhar Aurus is a good suggestion.
If you like the Evolution series, then go down to EL-P or FX-P. EL-P and FX-P are plenty fast but not as fast as MX-P. And if you have using 2.1-2.2 mm sponge for MX-P, then you step down to EL-P or FX-P, get the thinner sponge like 1.9-2.0mm.
