LP -12 Felt Plater Mat

I just restored my LP12, and am still using the felt mat. A number of poster's are saying various alternatives are "better" than the felt mat. Can somebody describe the effects of a different mat? Is it "better" or just a different "flavor", so to speak?

Happy New Year

As always I appreciate your responses.
I am not familiar with "Herbie's Way" or Boston Audio so more info on this would be nice.
I tried a ring mat and with good sonic results, but I returned it however because I could not justify paying that price for what I felt was construction paper with cork rings, and 2ndly, it was an aesthetic mis-match for my LP-12 platter.

The non-felt mat delivers much more air around the instruments with greater depth and width. The Boston does the same but to a slightly lesser degree, however, it seems to have more definition. When I exchange the Boston and the anti-felt, I like the one thats playing more than the one that I just listened to. They are both significant upgrades to the original felt mat. ..funny, when listening to the upgrades, the felt mat sounds "wooley". Comparing the non felt to the Boston - The Boston sounds like a top tier solid state amp, and the anti-felt sounds more tubes. Either one is a winner.

I went to the Boston web site and read with interest the info. I was shocked at the price but I think I'll try it anyway. Fortunately, I have two sons in college so my purchases are not impulsive, but well thought out. I'll keep you posted. Thanks, take care, and happy new year.
