Mitsubishi wire type setting for zinc coated wire

[Futurewire]

So, unfortunately the only options I have are. . .

0:BS
1:TN
2:SP
3:MD
4:HE
5:HF
6:SS
7:OM
8:HR
9:SR
10:MT

Any recommendations for which one to use with Zinc coated wire?

I'd be tempted to try them all to see if you get any differences.

However, sometimes zinc alloys can be refered to as spelter, so perhaps "SP" is the one to go for.....
