6 deck 17s LS sound good?
by 17s do you mean S17? Also, is there DAS? If so, the rules sound good but the one thing that can really make or break it is the penetration. If your getting more than a 1.5 decks cutoff i wouldn't play really no matter the rules. Aim for 1 or less if possible.
But for example, If 1.5 deck or less cutoff, S17, LS, DAS and you wong out then a 1-10 spread will beat it in the long run (using KO preferred correct?) assuming your counting is on point. If your able to get down a larger spread i still would try.
