I used them for years myself - great rhythm pics. Some guys use them really well for both rhythm and lead (actually, I was at an Urge Overkill concert and Eddie "King" Roeser uses them exclusively - I managed to get one after the show.)

Personally, I think they're great for rhythm, particularly with an acoustic guitar but they're not as good for lead or switching between rhythm and lead. The tortoise picks are far superior in this regard; they're thin enough to make even the most frenzied strumming fairly comfortable and stiff enough to give better control for lead. Not only that but they are made from some odd type of plastic that is completely slip resistant. Excellent picks.

I'm with Mr. Trouble. I used the gray (or black sometimes) nylon Dunlops for a few years when I started playing guitar, but have since switched to the green Dunlop Tortex picks, and even more recently switched to the Tortex "Sharps"

I don't like the Tortex picks. They feel to "hard" on the strings.

Now the Ultex picks I DO like. Except they are easy to lose.

I have a pile of different Dunlop Nylon picks. The .60s are a little thin for my taste, but I really like the .73s and .88s are GOLD.

I prefer the 346 Fender picks, myself. Dunlop has an Ultex 346 also, which is great and snappy.

I flip-flop between the 346 and the Dunlop Nylons for my favorite picks.

There are nylon cat's tongue picks, too. They are even easier to hold on to than the Dunlops.

Been using Herco Flex 50's for 15 years now,before that i used the red Riffs .73. I need to get some more in.

I just got my Dunlop 60s and my Herco Flex 50s and I think I prefer the Hercos by a thin margin. Both are easy to hang onto but the Herco has a tad more flex that I really like for snappy country tones.

I think I'm going to sacrifice one and file it to a super sharp point just to hear the results.

That's all I use - never drop'em when I play live, they never snap, they just do the job.

I use them and something very similar which I prefer - the snarling dog brain picks. I find them an even better grip. I like the red ones .73 and the black .88s. I got introduced to them when my oldest girl was studying barter systems in a 6th grade class. She took in her stuff to trade and came back with 3 or 4 black picks. I can't remember what she traded but at the time I felt she hadn't got a lot in return. Then I tried them and realized she's done great. They just don't fly out of the hands and they have a good feel on the attack.

Yes. It's my main pick.

I used to use these, but switched to heavier 1.14s (the pink ones). Now I find the edges on these .6s a little too sharp to give me that round fat jazz tone.
