I used to use heavy Dunlops, but gave up picks years ago. I like a grabby Knopfler-esque finger style, and I can get pinched harmonics using my index fingernail.

That's two votes for Dava. 
 
Here's a neat group picture from Dava that includes both of the picks mentioned.  I've never tried the Grip Tip Gel's yet...  Guess I'll have to now!
 
 

Make that 3 for Dava

 
GUITAR

• My go-to pick is a 2.94mm V-Picks 'Screamer'. Although it's both very thick and completely solid, it's incredibly comfortable to play with and, for me anyway, much more 'accurate' than a pick that has some give in it. I was put on to these by a guy who used to frequent the Guitar Tracks forum - CJ Linus (you remember him don't you James?) so I bought a 5 pick sample pack to try them out. Of all of them, the Screamer just seemed to 'fit', and I've stuck with them ever since.

 

• My next favourite, and the pick I used for years before discovering the V-Pick was the good old Dunlop Tortex 1.0mm. I still use these fairly often when I do need that little bit of 'give' in the attack.

 

• I also have a few of these Peavey 'Dreamer' 1.0mm picks, which are slightly more flexible than the Dunlop.

 

• For acoustic-style open chord strumming, my long time favourite is the 50mm Dunlop Tortex.

 
BASS

• Although I'm still trying to master playing bass with my fingers, my go-to pick for playing bass is a 70mm Planet Waves 'Duralin'. These just feel perfect to me, and nothing else I've tried comes close. The only problem with these is that they wear down really quickly.

I like Dava but have been using Snarling Dog Brain Picks for the last 2 or 3 years.  I use a variety of thicknesses.  My local shop carries onesies ... I originally tried them because even Dava picks tend to spin.  Theses are prickly on the grip and don't slip at all even with a light grasp.  Once I tried them, I like the material, flex, feel too.  Now my pick of choice
 

 

I usually use the green Tortex M3, which is pretty stiff.
For acoustic strumming stuff I´ve found that a really soft pick like the Tortex 0.5 mm. works well - almost like a natural compressor.
 
My son, who´s kind of a Django Reinhart-addict, made a bunch of his own picks from birch & pine, triangular, really thick & about 2" from corner to corner - took a while to get control over, but sounds pretty good - especially in his hands, in mine - not so good.

They give just the right amount of attack with the right amount of give don't they. It's a difficult concept to explain, but I'm glad I'm not the only one here who uses the 50mm for strumming, and for the same reasons

Bob, I'll have to try these, the superb grip of the V-Pick is one of the reasons I started using them in preference to 'traditional' pick.
 
Worst offender for me are those Planet Waves 70mm I use on bass. They are so shiny and smooth that I find it hard to play for more than a couple of minutes or so without the bloody thing spinning round to the thick end

YorOlPal, thanks I'll try that.

Currently I like V-Picks 'Screamer'. They are very expensive though. I like them for both electric and acoustic guitars.
