I recently got my 70k, the same 3-piece. I just use the canvas as it is. After about 500 laps (that means I probably used it a dozen times) it already feels softer. There's no need to do anything with it, in my opinion. It's a bit loud, but that's it. I've certainly not seen any ill effects on my edges.

Congrats on your acquisition, I feel it is worth every cent and I hope to buy another soon... for no rational reason! [emoji51]
