I just started using one recently when I got my TM. I think it helps although I have been thinking about adding Dovo White to it to maximize its performance.
If you own a fabric strap do you find yourself using it? I have recently found myself more fond of just the back side of the leather and then the topside.
The backside just plain or with one paste or another?
I have a TM with just the latigo and no fabric. I just bought a fabric strop. If I thought I could get by without the fabric and just use the back of the leather, I would be happy!
Use it everyday...usually 35 laps on it and 35 to 50 on the leather....
