Well, my first thought for clicks would be Prodigy. They rarely get the nod for suggestions when DGCR/Reddit is asked, however, I love almost every mold they make. (Hence a 90% Prodigy bag) BUT! They're still not "unpopular" enough for this discussion...
SO! Click: Discraft Nuke OS - Wicked overstable and not phenomenal glide, but the thing can RIP in wind! For years this was my only wind driver I'd carry. I can still get good distance with it on non-windy days and it's a great utility disc, but wind is where it shines and why it stayed in my bag for so long!
Clack: Overmolds. I know. I'm sorry MVP boys. I'm a Michigander, so, I SHOULD love my domestic manufacturer. However, I've tried so hard for years - buying every mold they've release up until this season - and have always shelved them. The Ion was the only click that I had from MVP/Axiom. It was a great mid with massive glide, but I couldn't stand it as a putter. What's worse is when it comes to Innova overmolds. I'd throw a Nova at a bonfire. That's about it. Hideous and flies like a dead bird.
