What Record Mat To Use With Music Hall MMF-5?

hi all - just curious what most forum members would recommend as the "best" record mat to use with a Music Hall MMF-5?

currently, i am using the stock felt mat that came with the TT and am quite happy with it...however, i am wondering what other forum members using different-type record mats w/ their MMF-5's or TT's might think?

thanx!

p.s. best way to clean felt mats is...?

 

I have tried the none-felt mat, but it tended to leave spots on my LPs that were very difficut to get off. It's a shame, because I thought it sounded very nice. I ended up making a home-made cork mat from some cork sheets I bought at Hobby Lobby.
