Graphtech's picks are good sounding. I had a pile of the deep and bright variants. I preferred the deep variant over the bright. My main complaint is they wear down too quickly for my needs. The deep variant really shines with acoustic guitars ime.
I think they're only about $1.25 each (you get a pack of 6 for $7 Canadian), and so, even if they wear a bit fast, compare that to on V-Pick at $5 or more... or picks from other 'custom' pick companies.
I've made mine out of a 4mm Steel rod/bar (whatever) I bought a few years ago. I haven't found any wear on them and they are no stainless steel... Cut to size/shape and grind and smooth the edges so it resembles a pick. Best picks ever, to me that is.
