Thanks for the advice eX Cess. I really appreciate your breakdown of the picks and their associated sound. I had been messing around with some 1mm picks my guitarist left behind and they seem to produce a very hard sound - but then again, much of that is likely due to my inexperienced hands. I am truly fascinated with the interaction of how the items that produce sound interact - much like how a drum stick and head combo (combined with technique and proper tuning of course) can really change how a drum sounds.
I have not yet given the Elixirs a try but I certainly will. I have had some decent luck with Martin SP 10-47s. They sound pretty decent so far! But I will give the Elixirs a shot when these need a change.
