In general I don't have an issue with the transmission on my '17GSA, (US size 11.5). When I miss a shift it is almost always created by a failure fully get pressure off the shifter. I swap between clutch shifting when I'm in the mood and quick shift when I'm not. Other than coming out 1st into 2nd where I always clutch, all other gear changes are smooth with either manual or quick shift.
This is one of those things though that depend on the rider so I'm a big fan of everyone doing what works for them.
