Worried about H17?
That's only worth about -0.19%. Don't be penny wise & dollar foolish, and take a look at the difference in 80% pen vs 60%. Depending on the game (you didn't give the specifics of the game available to you), the 80% pen could have an EV around 1.5 to 2 times higher than the same game with 60% pen.
Always remember the three most important game rules/conditions with respect towards EV:
1. Good pen
2. Good pen
3. Good pen
The next on my list would be hands/hr. Bet size/spreads tolerated would also be high priority. Rules such as H17, RSA, DAS, etc. are certainly worth consideration and you should always adjust to the correct play for the rules of a particuliar game, but these more common rules variations are generally far down the list in importance to EV. An exception might be 2-1 or even money BJ payoffs, which are worth plus & minus 2.3% respectively compared to the normal 3-2 payoff, and maybe ES, all of which I don't consider "common variations" anyway.
