I have a jolt solid and a tropical storm. Both really nice balls for the right conditions.
My Jolt has a 2" pin-PAP and is probably the smoother of the two reacting earlier but more of a hook-set type affair.
The tropical has a RICO drilling and that goes ok. It tends to be a little more angular, doing almost nothing for most of the lane and nipping in in the last 8 feet or so. Great for playing a dry outside line, can be a little so-so on shorter oils.
Don't know much about the pearl, but if it's anything like the solid, it'll be a decent ball. The only downside to my jolt is it tends to track up awfully fast, like my old x-factor deuce did. So bear that in mind.
