What would you all say are the best now? Z FLX and Jawbreaker are now in production. What's best for putting? For drives?
To make a short story long: last year (2015) I tried the Challenger. Liked the putter, the Pro-D plastic was nice and firm, but the Pro-D plastic did not last hardly two rounds. Really nicked up just from throwing into the chains for 36 holes. All other plastics were too soft for my liking. I got a Titanium FLX (misprint), and while I love Titanium plastic, the"FLX" made it too soft for my liking. Alas, foiled again.
Then came the Jawbreaker plastic. It's a lot like Classic Blend/Zero Medium from Trilogy. Classic Blend starts out nice and firm like I like, but with use it softens up... so I went to Classic (Hard)/Zero Hard, and I really like that.
But I tried a Jawbreaker Challenger, and then got a second one. The Jawbreaker plastic is more durable than Pro-D... I've been using my Jawbreaker Challenger for several weeks now, and it's about like Classic Blend (and Classic) in the wear-and-tear department, which is okay.
In addition, the Jawbreaker plastic has held up in firmness, so far. Feels as firm as when it started out. That may change over time, but so far I'm happy with the Jawbreaker plastic, and I'm having a 'putting honeymoon' with it.
I can't speak for throwing (i.e. not just putting) with it, as I don't use it as a throwing putter. If I were to adopt the Challenger as my primary putter, I might give the Titanium FLX another go as a throwing putter, though, just to have the same mold....
As ever: JMHO, YMMV.
