SS Magic.....grippy and firm enough stay on a line for my throw....soft enough to absorb some energy upon impact. This is big for my style of trying to miss a putt ; ) ...a putt is a little high and off center....a harder disc will likely deflect out and away....a softer disc will tend to absorb some of that impact, stop in it's tracks and drop straight down.
the SS Magic is the best disc in my bag when it's wet and rainy
Longer Putts - Soft Magnets. I love the feel of them (unless it is over 90 degrees, then they start to melt). For spin putts they seem to hold the perfect flat line.
Inside the Circle - Chalky SS Wizards. Still my favorite overall putter. Not as soft as the magnets, but still a good texture for my hands. I always feel like I get a good smooth release on these, no matter the weather.
I use an APX swirl for the majority of my putting and a JK-Pro Aviar. The Aviar is more stable so I use it for windy days and or long up shots. The APX swirl has a nice grippy feel, but is still fairly ridgid and it's a nice straight putter. I tell ya, the more I play and figure out this game. You can make a less stable putter handle most of the work. I think it's a mind game.
proline rhyno -- soft and stable, for aggressive line-drive putting. also the best headwind putter. rhynos are meant to be putted with conviction, choose something less stable if you aren't feeling it.
soft photon challenger -- straddles, jump putts, and tailwind, this putter flies dead straight with a softer release.
IMO you can never go wrong with a Pro Rhyno (I have 5). I putt with a
170g and throw short upshots with a 174g. Grips really nice. It's not
too soft and not too hard. Of course I don't have sex with mine so I
might not love them as much as I thought! :)
