Mintylamb <mintylamb.co.uk> has a needle chart you can use to look at
the different profiles. My suggestion is you start with the standard AN
needles and then try M needles. My guess is the M (Cooper S) needles
will suit you best.
Also, remember to try red and blue springs as the spring rate may be
different from standard.
Cheers,
Martyn
