Well the SR2 is a polished finish and definitely goes longer than the GT1 and has a similar look to my pearlized equipment. What I like about it is it doesn't skate in oil the way most pearls do, but I still have that same long and strong look that my pearl equipment does.
It's very similar to the virtual energy and some other pearl equipment I've thrown but hits much harder.
Ironically I used to throw all Morich equipment so I have a lot of experience with their covers and cores. I've had the Seek and destroy, levrg, sahara, ntense levrg etc. The one thing I'll say about Mo equipment, is even with pearlized coverstocks you'll never get that long pearl look. The cores are so big, heavy, and strong that there's no skid snap look to Mo equipment even with a pearlized coverstock that I've found.
I still like their equipment but with no PBA support and the whole Mexico thing I've decided to move on from them. I don't know much about the seismic or AZO stuff.
Anyway good luck with whatever you decide, hopefully some of this was helpful!
