When I purchased my TS 75 in November I was somewhat disappointed with the way that the saw became so unbalanced while cutting a 45 degree bevel. My first thought was to use a heavy piece of steel to compensate for the saw's tendency to tip off the guild rail. My solution was to use these lead shot filled bags that I had laying around.
These little bags called Seabags are weight bags used for scuba diving. I found that 21 lbs work just fine for my saw tilted to 45 degrees. (3-5 pounders and 2-3 pounders. These are expensive but worth it in the scheme of things Festool.
I am new to festool but so far I have the TS 75, MFT/3, and a ETS 150/3. I don't go near green Kool-ade but I do eat green popsycles. I went to Home Depot to buy masking tape and I came home with a roll of Frog Tape.
