I started using the SParms sleeves. They are 50+ protection, plus when I sweat, they actually keep my arms cooler in this Houston heat and humidity. Reminds me of farmers and ranchers I saw growing up - they wore long-sleeved shirts in the middle of summer for much the same reason.
Please consider me for the putter testing. I've been going through putters and would like to test this one. I hope it's a great putter.
