Back-counting with KO

#1
My buddy of mine is starting to get into counting, but insists on using an unbalanced count, as he is worried about dividing, etc at the table. I know you will have to TC to figure out when to leave the shoe, but what would be the wong-in point in the following game?

H17, DAS, RSA, 5/6, no surrender

I believe the advantage swings to the player in this game at -3, but to be risk averse, 0 isn't too far away.

Also, if anyone does have a spare minute, I don't have the program, and figured optimal bet out myself for my BR, but he has a 7k BR, and want's to keep his risk low.
