These are not assigned flight numbers yet but are approximately a 3/4/0/1 for my very average arm.
 
Our first beadless putter flies dead straight at slow speeds giving it a true flight, reducing missed putts to the left and right. At higher speeds it flips up slightly before flying straight but then flies true with a slow fade at the end making it easy to control distance.
 
Strato plastic - Our "putter plastic" is tacky, grippy and won't slip out of your hand, wet or dry. It's not stiff, but not floppy either. It's a medium softness that just feels good.
