I have a SSS Wizard, (Super Stupid Soft) that I use for puts 30 feet and closer that flies dead striaght.
At 30 ft. and closer it really doesn't matter what putter you use, it's 30 ft.
Driving with putters will tell you the true flight path of it. Having said that, I've putted and drove with Magics, Wizards and Voodoos for a long time. Warlocks seem like a useless mold. Sorry, personal opinion only. All I know is they are supposed to be out of the box beat in wizard-like flight paths. If that's the case, I'll stick with a true beat in wizard for consistency.
Wizards are overstable and very predictable, as they age the juice only gets sweeter. These have a bead if you like or dislike beaded molds.
Magics are understable, if you turn one over too much, you can kiss it goodbye, it is not fading back. Can be a good/bad thing depending on your play style. No bead. Best putter ever made for actual putting duties IMO.
Voodoos lie in between the first two in stability. Tiny bead.
As far as plastics go, Gateway has some great putter molds but they're pretty inconsistent with plastic. You can get a floppy SSS one day then order another that will still say SSS but be as firm as a Soft and vice versa. It's a marketing ploy to get you to by multiples of the same mold hoping for that perfect feeling disc.
The eraser like Softs are money.
