SU 1 3/4", needles for standard 280ZX?

[Broughton]

Would appreciate suggestions for needles to suit twin 1 3/4" SU's on standard 280ZX build.
Have seen SM needles (fixed type) suggested but my carbs are HIF which have floating needle type.
Nearest profile to SM I can find in the floating needle range is BCH.
Not a speed freak just need needles to give best all round performance.
Any offers?

Perhaps ask Burlen?

Thanks. Tried that and they say they have no particular recommendation but hear the SM needle (possibly modified) has been used by some.

This might throw some light or just make things more confused!

Thanks Toopy. Now that's a good read for a long winter's night but all a bit too techy for this numpty. Just hopeful someone has done it and can give me off the shelf advice.
