Personally, I think it is a good idea to experiment with different picks. There are many recommendations, and some are based upon playing rhythm, or lead guitar. To me, picks have two important qualities:
"Feel", and
"the sound produced". You might like a thin or thick pick, of whatever overall size, which is pointed (to get a sharp attack and resultant sound) or rounded (to produce a more mellow sound).
As I have said before, I like the concept of
"having your own sound". If you settle on a specific pick, that is a plus in my book. Otherwise, you might have difficulty trying to remember which pick to use with which guitar, to play a piece of music on your guitar, too be "authentic".
I did recommend a line of picks about a year ago, which resulted in a member
BLOCKING me. If anyone wishes to block me for whatever reason, please feel free to do so. But it would be greatly appreciated if you are civil about it.
