which gearbox oil should i use?

[Phased]

Ok,

Phased- never used neo engine oil to be honest, only gearbox.. Out of all the oils for engines, I'm a fan of FUCHS 10-40, it's made for jap performance engines, and high revving engines, and it's cheaper than most oils too, eg castrol edge..(which I like too)

When I had my integra rebuilt after 1500kms I was using Fuchs GTO 10w30 Semi-Synthetic. I liked it. Then after 10,000kms switched to full synthetics. Had Motul 300V Full-Synthetic in there and dispised it. Changed it after 1200kms. Made the engine very chattery/lacked response down low. It was the same viscosity too. It's been Royal Purple ever since.

I wouldn't mind trying out neo, expessially for the summer as you can actually obtain the 10w30 in Australia unlike Royal Purple. However, I can't get past what mechanics have told me. So I really want to get Amsoil but I can't for the life of me find a retail outlet in melbourne.
