Canter transition with a horse heavy on the forehand

I have an Andalusian who is very heavy on the hand and often looses his balance in canter. We do a 20m circle, in trot, then leg yield him towards the outside rein, bending him around the leg, and then the canter transition is very smooth, not pulling me out of the saddle. This is a successful one, there are lots of ones that don’t go as planned 😂
