Just wondering if your dificulty with the centrestand could be technique. You shouldn't need strength or height to get it up onto the stand. The 'work' is done with your foot, your hand (and back) shouldn't have to do much more than a slight lift and guide it back.
We all assume that everyone knows how to do it but that's nor always the case. I remember getting my first road bike, a CB900F, and thinking at the time that there was no way I could get that huge bike up onto the stand untill someone showed me the correct technique.
This is how we instructed novice riders to do it:
Stand close to and facing the side of the bike. Left hand on the handlebar, right hand on the lifting handle and right foot firmly on the centrestand.
Push down firmly on the centre stand with your right foot while holding the handlebars straight with your left hand and lifting up and back with your right hand.
Things to check: Front brake off, bike in neutral (it needs to be able to roll back).
If the bike feels like it might fall away from you during the process just push down hard on the centrestand and the 2 feet will keep it level.
Cheers
