And I like my Tortex Flex Jazz XL picks mirror- polished ?
The Flex combines Tortex with Nylon and sounds very nice and balanced. The thicker the better here for me, so I like the 1.5mm (and 1.35) best.
The grip is not as good as pure Tortex unfortunately. I get the best grip with this pick by polishing up the mat surface - now it sticks to clean fingers. A bit like acryl picks.
I polish the edges too and the already silky feel while playing is even more pleasurable.
These are very cheap, but sound and play like the best boutique picks available now
