I have the Callaway Paradym and Cobra LTDx(not the Max or LS). The Paradym is very long and the straightest hitting fw club I've ever used. But I do think the LTDx is a longer club. I do have different shafts in them, so it may be for that reason.
Both are the smaller head, not the 'pancake' heads of the Max category. Shallow-medium face depth, not deep. Both easy to hit from fw or rough.
LTDx can be had new as cheap as anything used right now, if you can find them with the shaft you like.
That all said, I will never give up my Callaway Diablo Octane Tour. Henrik Stenson had one til he finally busted it.
I do use all 3 in rotation though. All very good, easy to hit well!
And FYI.....I'm not married to the Cobra or Cally.😄
