Have the Strike King for over 2 years now put an weight hole in it year and half ago brought it to about 1/2 negative it let's me play as long I can find some head oil so far haven't had any problems with dry lanes since the change.

SuperNatural?

Man, weaker than a Tropical Heat? That may be tough to find in resin. I'm mostly a Brunswick/DV8/Radical guy at this point, but I still have the Tropical Heat pearl in my bag as a dry lane/spare ball. I took the surface on mine down to 500 to smooth it out and take away over/under, and I have been using it in place of my T-Zone as a spare ball. To me, the Strike King was noticeably stronger than my Trop. Heat. It still wasn't a "strong" ball by any stretch, but it was more ball than my Trop.

I would also vote for the ride.  Out of the box I could line up with it off my blue hammer.  High rg and low flare almost make it act like a 3 piece ball.   I have had really good luck with mine on fresh house shots.  Much like urethane, you have to be able to square up with it.  If I have to move in and go away much at all, the hit really drops off.  If I can stay outside 10 board it will roll up hard, but more important it will find some hold area that would be non existent for any of my stronger stuff.   

Here's a few to consider from 900 Global: Boo-Yah! has a urethane cover, Chemical X has a medium strength cover and a low diff core for less flare, and the Break Down with a low diff core for less flare as well and a stronger cover over the Chemical X. Each of these will easily fill the roll as a low flaring ball. These also are very drill friendly, put your favorite layout on and they are ready to attack the lanes. Not to mention they are at reasonable price points as well. Hope this helps.

good timing on this post. I'm also looking for something for second shift league. My lowest flare ball has a hard timing staying right. And when I start moving in, I tend to get trapped with this ball. I can use other balls to play inside the track, but that leaves a lot of corners for me. Straighter angles gives me better carry percentage.

Sometimes guys can play outside, up the boards when the broken pattern is pushed out, but my equipment that I have all check up early - unless I throw like McCune.

Right now, I'm looking at the T Breeze...

Best second shift league ball I have used is the 900 global Breakdown, but with a low flaring drill on it.  This causes a already low flaring ball to flare less....I would worry on the Chemical X as both of mine flare a little and hook more than my low flaring drilled breakdown.
