Why not start with a BDL, which is the starting point for an MG Metro. That's what I used to start in my 1293 and also the wife's 1330.
You could ask AC Dodd if he has a tuning day coming up; he's in Salisbury.

Ah, maybe BDL is not such a good idea as it could be too rich. Maybe 2x BDF. AC Dodd doesn't do twins I don't think.

If you are looking for fixed needles in twin HS6 then suggest trying KW which I found a reasonable starting point for 1380 running 286 with 1.5 rockers.
