New to counting - need advice!

Would like to know if the following system and conditions yields a positive expectation and if so, how much is advantage? (Couldn't find a good simulator to tell me)

Count method is (2 thru 6 = +1, 10 thru A = -1, 7-9 are neutral)

Conditions:

6 Deck Shoe
Dealer stands on any 17
Can double down on any hand
Can double after any split pair except Aces
No surrender
BJ pays 3:2
Insurance available on dealer Ace

Thanks for your help!!
