BS Divations for 5 card 21 Bonus?

Does anybody have any info on multi-card BS divations for a game that offers a 2:1 payout for a 5 card 21?

The rules are as follows:-

8D
S17
D8-11 only
DAS
no resplits
no splitting A's
NS
Peek

BJ - 3:2
Suited BJ - 2:1
5 card 21 - 2:1

Thanks

Guessing I would say definitely:
Hit a 4 card 16 vs 10
Hit a 4 card soft 18 vs A
Hit a 4 card 12 vs 4
and probably:
Hit 4 card 13 vs 2
Hit 4 card 12 vs 6
and possibly:
Hit 4 card 13 vs 3
Hit 4 card 12 vs 5
