Just caught this...What do you mean.."cut down e-ring"?
Can't wait to see some pictures of your kit Yamahamer.
About the cut down e-ring, I bought an Evans E-ring for my 16" floor tom, but I found the ring dampened it waaay too much, so I cut it to abot 1/2" thick. Probably would have been easier to buy moongels, but oh well. I already had the e-ring.
