Used RPS Polar Ice yesterday up at NPF Birmingham... It was absolutely AMAZING.
I spent the 2 hour drive up to Birmingham wondering why i was bothering as i was sure i was going to spend a day perfecting my squeegee technique and 2 hours driving back at the end of the day marvelling at how i'd only had one break all day which was in the breech (i think due to my hopper crushing the ball) and yet every ball i shot that hit a player broke on impact.
I've never used Polar Ice before and am pretty impressed with it. I didn't even bother trying to keep it warm so it spent the day in an open box of paint in temperatures near freezing... As it went through the day more flat spots started to appear and accuracy gradually got worse but still no breaks!
Very, very impressed!
