There is nothing wrong with their mounting system. It's just not what some people prefer; you get that with every drum company. Some people like Pearl's tom arms; some can't stand them. It's no different with Sonor, Mapex, Yamaha, etc...search the net and you will see complaints about every manufacture regarding their mounting system.Force 3007 it is! Going to order the 5-piece and look for another floor tom. Can't go wrong with Sonor A bit worried about some peoples comments about their mounting system..but we'll see....
I've had the 3007s since they first came out. All the hardware, and the tom arms and mounts in particular, is still holding up and I play them everyday. The drums sound great and are easy to tune. I'd almost guaruntee you will be thrilled with them.
And no, you can't go wrong with Sonor.
