Weight for backing?

I would say that depending on the horse that 10st would probs be a fair maximum for an introduction but balance is more important than weight so as long as whoever is on board is a quite tactful rider then that is the main priority
 
my friend who backed my welshie was about 10 stone BUT i'm considerably more than that and took over the ride a month later. agree, a balanced experienced rider rides lighter.
