I received the TC97 18/20, 320, 310mm today. The shipment was super fast!
I have mine with leather grip. Weight 323g which is perfectly fine. I strung it up with Big Hitter Silver 1.25, 22kg. Overgripped with Tourna and strung weight came to 346g. Strung balance is 31.4cm which I expected to be roughly 32cm - like Prestiges are. I have to admit I forgot to check unstrung balance. I measured the swing weight 331 which is like I expected.
I hope to be able to hit the courts soonest. However few of the average 50 rain days will happen tomorrow and beginning of next week

. Also my left wrist is still after two months not usable due to the fracture so I will keep slicing.
I had few feel hits in my garage and the feel is soft / smooth. If you have hit with foam filled old school frames it feels familiar. POGs have it, older Prestiges have it... Perhaps it is a little more wobbly towards edges of hoop in comaprison to iPrestige and Graphene Prestige. But I can believe it to deliver on the courts.
My only worry is the balance. With 31.4 cm I mostly likely will lack with serves. Now there is room to add weight to hoop as SW is 331 but I prefer not to add much if any. Lets see. Third world problems but then again it is what this thread and other are about.
I will write up once I have properly played with it.
Hasta luego!
