not a mechanic but changing cloth also...
I am also curious if mechanics recommend anything other than Simonis for a home table - it seems there must be some good cloth out there that is not quite as expensive as Simonis yet still plays well and gives good life. Simonis has about priced itself out of my social security retiree budget, even for an 8-foot table it costs nearly $300 at internet retailers..
I probably should not complain about price, though, since Simonis 860 now on the table has given me well over 7 years of service and would not need replacing except A. there are a few tiny 1/16" or smaller wear holes up at the head of the table, and B. I made it ugly by putting down some Permanent Adhesive hole reinforcements I bought at Walmart - they proceeded to make dirt rings every where I put them, and the ugly dark dirt rings did not show up until several days after I removed the little buggers.
I have found no chalk that is the same color as Tournament Blue Simonis. I tried Master Green, the one that looks Turquoise, and hated what it did to my cloth, cue ferrules and shafts, and my hands. I switched to some old Pewter Gray Silver Cup I had laying around and it is currently my favorite along with Tan Silver Cup. Neither the Pewter Gray nor the Tan Silver Cup mark up the table or the cues or me. I am now trying some Gray Master chalk and so far so good, cloth stays clean as do the cues.
My used table came with Red cloth - red and burgundy seem popular for home furniture tables. Big problem - Red or Burgundy chalk will really really screw up the ferrule on all your cues and anything else it comes in contact with. Due to the Ugly factor, I stay away from any Red chalk, Dark Blue chalk and a few other colors including Green Master.
