I'm looking at the exact same decision. The issue of symmetrical vs asym is huge for me if both balls give identical performance, since I've never met an asym I really like with the possible exception of my SureLock. So, if they are the same or even close, my choice is made.
OP, what's your stats? Here's the problem. The Forge Flare looks way early and to my eye deflects too much. Being a low rev lefty where everything looks like a flood, I fear the Flare will die at my feet.
