I just got hold of a Hex and a Voodoo and can also get a Pearl Stomp.  The Stomp is well before I started throwing Track so I don't know much about it.  It looks like it has the same core but a stronger cover (according to Track's website).  How strong is the Pearl Stomp and is it worth getting if I have both the Hex and Voodoo?  I don't want too much overlap.  Is it stronger than the Hex?
