I put a set of Tomastic flatwounds on my Jazz last week to see how they play. While they are smooth and have a rubbery feel, I found that they slowed my hand down. It seems that having more surface area on the flatwounds makes it more difficult to skim over the surface. As my hand became more sweaty the longer I played, the strings got stickier and slower. Has anyone else found this to be true or is my technique at fault?
