Efficiency of H17 strategy at S17

I don't own any sim programs; perhaps someone could help me out. If I have a basic strategy and Hi-Lo I18 tailored for a H17 DAS D8 single-deck game, what is the difference in EV between using the H17 strategy at a S17 table, and memorizing a new strategy and indices specifically for the S17 game? Assume a 1-5 spread and whatever penetration they give at the Vegas casino I'm talking about.

In other words, I'm wondering whether it's worth it to memorize the different strategy for the appealing but uncommon SD S17 game.
