I use these picks with ES175 type hollowbody guitars, playing Be-bop, Gypsy and smooth type jazz.
These picks are very substantial feeling at 3mm, but one side has a nice feeling thumb indent. Overall it may be worth trying a number of these picks, as the have a range of different styles, some with a sharper pick edge, whereas this one obviously has a fairly blunt pick edge.
Relatively expensive, so you end up looking after them slightly better - I haven't lost one yet!!
