You have obviously tried a variety of combinations and if you have a better idea, I'm listening.

I have tried, 15/45, 15/46, 15/47, 15/48, 16/45, 16/46.
I would try 16/46, that will give you a better cruise speed. I found 16/45 to tall for me, great if you want to cruise at 130/140KPH.

You can buy 16T in Oz.
