I bought a 12 pack of the 1mm, by far the best grip of any grip pick I've used (e.g. George Dennis, Brain), and nice smooth finished edge, but way too much flex for a 1mm pick in my opinion. I guess because they're nylon. The 1.14 might be closer to a 1mm made with other materials. For comparison, Dunlop Tortex .88, George Dennis 1mm, and Brain 1mm are all noticeably stiffer than this pick. I'm also curious why there are no thickness increments between 1.14 and 1.5mm, that seems like a big jump.
Constoo much flex
limited thickness choices above 1mm
