well I have both TBS and viscaria (both black tag) and they play totally different. Untill I tried them both I also thought they should be basically the same just looking at construction, but the TBS I have is a lot more direct and I love it for bh, but not so much fh, but viscaria is a totall opposite, I love it for my fh and a little less on bh. I used same rubbers on them (dig05 and 09c). Have no idea why, but if I didn't know about their construction I would never have guessed they are "the same"
