dignics 64

Does anyone have any experience with the 3 of these BTY rubbers in comparison with something like a Fastarc C-1, Rakza 7, Vega Pro, Hexer(old tensors) as I'm familiar with that class of rubbers for BH. My current sheet of Vega Pro is dead and wanted to see how the T19 and D80/D64 compare. I know...
