With being a little speed dominant, if you have a decent rev rate, it could work well. Just keep in mind that the Primal Fear, just like the Primal Rage are going to be very angular balls. You might need to change the surface slightly with knocking off some polish or potentially using a stronger layout to get it to fit.
Having thrown the original Revolt, the Havoc uses the same core but has a stronger solid cover. The original works well for me as I can throw it firmer and play straighter while still having plenty of movement downlane. It also works well on medium THS but will handle some heavier volumes. The Havoc is definitely good on the THS, but will handle even more volume. If you were to compare to Storm, think of it as being similar to the Marvel-S.
