The TRC is a great "hybrid" type club that has been discontinued. I think it is actually a far better performing and looking club than the Mid. I found success with an Aldila NV-95 "S" in my TRC. I also added a half inch to gain a few extra yards for par 5 reachability. So bottom line, I would stay with a slightly heavier graphite gram weight in the 85-95 zone and mid flex point. This would match the weight and characteristics of the TRC design. IMO
When you refer to the Mid is that the Md Transition club?
