After discovering I had an allergy to traditional silver plated mouthpieces, I went through a few alternatives (gold plate, stainless, plastic rim) with no success.

I decided to take a gamble and try the Pickett 2 piece system with an all Acrylic top.

After 6 months of playing Pickett I can gladly say that this has been the best alternative that I have found. The rim is comfortable/easy to adjust to and I found no apparent loss of sound due to the acrylic top.

I definetly suggest this option to anyone who has a severe metal allergy.
