just an idea..

Obviously i just whipped this up super quick with images from the net, but I thought this basic design, just refined would be pretty neat... and add ULT in dead space, or swap around ULT space and lvl x etc

This would also work well on a taller size mat, the valve images could be huge like this... you could also get the LVL x stuff taken out of the x valve picture, that would open up more room to make the image bigger, plus not look so cluttered with 4 different bolt images and break downs....
