As I want to convert my 18x16, and 16x16 toms into bass drums, I want to get a Jungle Gig Adapter and Optimount (16x16 has a wood hoop, so ISS will not work). I've seen in the price list the normal Optimounts and so called New Optimounts. The old ones are like 20 bucks cheaper. Has someone had to do with them and could tell the difference? I want a solid mount that will last for years.
