fastarc c-1

I have been using a 2.0mm Fastarc G1 for FH and 2.0mm Fastarc P1 for BH on a Viscaria SALC and so far I am finding positive results. G1 stays on my FH fs but I will upgrade it to MAX thickness. However, on my backhand, the P1 feels a little bouncy in the short game and I suck at the short game...

Searched as much as I could and it's pretty hard to find a direct comparison between the two. Esp since C1 doesn't seem as popular. For someone returning to TT after some time off (since pandemic) which of the two rubbers (C1 or R7) would you recommend for both wings of a Korbel blade, and why...
