Go for it, guys!
I "did my thing" on my own without the benefit of help or high-tech wizardry. I imagined what I needed to replace the horrible remnants of the foam pad I found in my F-122 and bought something that was local and cheap. Colorful and interesting was a bonus.
I had done an AT and a couple of XTs previously, and the mats were acceptable, so I did not worry about it until I got a really bad one.
Personally, I really like the art mats and think that the extra thickness and density helps to contain the excessive pinginess of the Model F, and gives a very solid feel to the board which I like. The downside is that it makes the assembly very hard to slide fit back together.
If you can accomplish this, I think that the result is great. But considerably thicker, softer mats may well be much easier to work with. I am a big strong guy with big strong hands and I am not afraid to use tools like serious clamps and hammers, but if you are intimidated by wrestling with these components, then a more pliable and forgiving mat is in order.
