re. the NBHW needle

my set up is:

'06 EC 200
NBHW needle 2nd clip
slow #45
main #175
airscrew 1 1/2 out
1.2mm squish
recent piston rings
boyeson carbon fibre reeds
fmf gnarly pipe
13/50 gearing, trail, tops out around 70 mph and around 70 miles to the tank
13/52 gearing, race, tops out around 60 mph
standard uk pump petrol mixed at 45:1 fully synth

My question is does anyone know of a needle similar to the NB*HW, but with a slightly narrower straight section ? I make the straight section to be 2.89mm dia., which I suspect to be a touch lean and the reason why the tickover screw needs to be wound in as far as it will go to get it to tickover. Other than that small failing, it runs great with the above set up. The surface is starting to pit on my needle, so it needs replacing and it would be good to get the tickover back into the middle of adjustment.

*the 'B' is weird looking, like an upside down greek beta letter, but I'm fairly sure this is the needle this bike came from GG with.
