I went to one of Jack's paddle demo events and you really learn a lot. He brings 100+ demo paddles with a every combination of core, surface, and weight for you to try. Every combination of core, surface, and weight has a different feel and pop which is why every pickleball player must try one of Jack's paddle demo events. I thought I was a light weight, Nomex core, Graphite surface paddle guy until I found the perfect mid-weight, poly core, carbon fiber face paddle with custom grip for me. Just a whole new level of a paddle buying experience.
