Hello peoplez!
Trust me to get a word in on this topic!!
First up, most balls people use these days (that is, the high enders) have RG avgs below 5.
The attack zone you mentioned, being a entry level reactive, has a much higher rg though, 8.7. No 18 board hook there!! Unless you're on very dry lanes!
I've used both the Messenger Ti and the Messenger Ti Pearl. If you can get your hands on a Ti Pearl, do it. My opinion is that the original Mesgr Ti tends to be less "user friendly".
Urm... if you want a Vortex Afterburner... come find me, I've got one to let go! Heh
