thanks guys!!

heliTB - what's your max/min on your pitch curve and when do things start to bog?

Both of you: what are your needle settings with the Hatori pipe?

I have a hatori pipe in the post but it has a different model number to sab 6rs but it looks the same in the pictures - are they actually the same - (mine's a Hatori 415 for OS37/caliber 30)

+/-11 is wicked!! I can't wait till i get my pipe! Things are struggling in FFF let alone stall turns etc.......
