I've done a *lot* of experimentation with different pick types over the past few months.....so far, I like:
and
Pickboy picks are hard to find in my area. A local store finally got some in, but not in the gagues I wanted.
The .88s aren't bad, but I would prefer the body to be a tad thicker. I'd also like to try some of the Pos-a-Grip and Pos-a-Jazz models as well.

The Dunlop Jazztone 208 is an awesome pick....it's a big honkin' THICK pick with a nice pointed tip. Not sure what the surface is, but very grippable. I like these a lot, but sometimes they can produce an overtone. Again, hard to find in stores.

So far, I'd have to say this one is my all time favorite. You hear a lot about the
Dunlop Jazz III, but I much prefer it's slightly larger brother, the Jazz III XL. Perfect shape. I'd like to see Dunlop come out with a Gator Grip and Ultex version just for comparison, but I'm not holding my breath. Again, very hard to find in stores. I seem to have a knack for liking "exotic" picks.
And still yet, there are a BUNCH that I'd like to try that I haven't found yet. The Planet Waves Surepick. The
Ibanez Paul Gilbert, Steve Vai, Sandgrip, and Rubber Grip models.
The Gripick
Awe-In-One
Brossard Picks (wooden)
Kradl Guitar Picks
MacPherson Graphite (only available at Guitarpickcentral.com)
Fernades PPS picks These are pretty good, too. I got a sample 0.8 mm regular, and it has a pebbled field at the top for grip. I'd like to try the 1.0 and jazz versions.
Clayton Black Jazz I've only tried the regular Acetyl Claytons....haven't quite decided if I like them or not....
Wegens Picks
Surfpick
And these are just some examples of ones not normally found in shops that I'd like to try. I've purposefully left several out for brevity's sake.
Of the more common ones, the Dunlop Gator Grip 1.5mm (oddly, the 2.0 mm seems to create the occasional unwanted overtone) and the Ultex 1.14 are both very good.
If anyone has tried any of the above models (or others, for that matter), I'd love to hear a discussion about them.
