NGK 9's if you can find them, and u have $$$
071's otherwise, both will be fine.
Nothing wrong with C57's IMO, apart from a bit of a crappy idle, which you will no doubt know about already if you are using them,
I've used C57's and laterly 071's on Stu's reccomendation, with no complaints either way, the idle is clean and smooth with 701's though
I've only got stg1 4x4 though, and not willing to shell out $$$ on 9's when the 071's do the job just fine

The R 7234-9 works very well on standard cossies & tuned/big power YB engines Not cheap, but a good investment in the long term (IF you can still get them - as they may be discontinued now).
