Seems to be the general thinking... I was just going raw off the manuals because my existing (comprehensive) set of steel pinions aren't long enough and I didn't want to go out and buy all ten 17 - 27 pinions for trial and error lol.

Am trying to source some Corally long pinions in 20, 21, 26, 27 and a AE T4 87T spur... haha and I thought my build was close to complete...
