The "discontinued" Workshop series are the same exact shells as the collectors(except for the reinforcement rings) You can order DW with or without them. The reinforcement rings actually make a higher pitched tone which i don't really care for. But anyways you can't go wrong for $1,000 trust me.
Well, actually that's not fully true. When the reinforcement rings are used, it allows for few plys, which means a thinner shell, which means a deeper tone. It all depends on the number of plies in combination with or without the reinforcement rings. I don't think we can make a blanket statement that drums with reinforcement rings sound higher; there's too many variables ... some of which I haven't mentioned.
