My Aramith Tournament Duramith's play very similar to my new Challenger's, although they get dirtier slightly faster. My Duramiths are fairly new though as I would think they only have about 10-12 hrs play on them. The Challengers I now have about three weeks on them with about a half hr a day play and have yet to clean them. I did play with my Duramiths a couple days to compare and not much of a noticeable difference other than the Duramiths didn't stay as clean. I think the break difference I noticed when first playing with them was more in line with them being new vs the Aramith Premiums I had used for 7 years or so. I really love how clean they stay vs the Aramiths.
I was cleaning my Aramiths every week and a half to two weeks, and I would assume it will be every 3-4 weeks now with the Challengers, but I don't chalk as much at home vs at league, In fact I almost never chalk for breaking at home, and maybe once every 5 shots or so when playing.
