Combining RPC (or hi-lo) and Ace-Five

[BothRPCA5]

I have been using a combination of RPC (one might use hi-lo instead) and ace-five, such that I potentiate the bet increases dictated by RPC if the ace-five count is two or more. My local casino offers ENHC, DAS, no surrender, resplit aces or others endlessly, about 80% penetration, 6 decks, S17.

Am I wasting my time with this added procedure?
If there is value to the combination of RPC and ace-five, is there a better approach, such as the sum of TC and ace-five as a modified TC (perhaps only if ace-five is non-negative)?

thank you.
