Thanks Dash6, I think the TC is Ok as it is centralised when parked on level ground.
And yes our 172 has got the rudder trimmer on the consul.
It's just that we can either have one or the other in trim, but not both. I may Velcro a removable small lead weight to the right hand side of the Yoke... just a couple of ounces should do the trick..!
I also have access to a glider that has a novel pitch trim arrangement; It uses a spring on the stick, which can be 'zeroed' once you have held the stick in the desired position.
