Saddle problem - ideas

[doonrocket]

I have quite a wide young horse who I am currently riding in an extra wide cob T6 thorough good. It's a nice saddle but I'm not the biggest fan. It slips even with an anti slip pad, although professionaly fitted.

It's a bit of a challenge as the main reason it slips is his right shoulder currently has less muscle in it than the left.

Normally I would ride on the right rein to try and build it up , but his left rein is his most unballanced and the one he really needs to be ridden on, (Bit of a catch 22!).

Choices are H&C cut saddle at some expense, continuing with what I've got but just concentrate on Hacking in straight lines while he grows - or your sugestions...

get a (good) back person out. The muscle wastage could mean there is something 'out'. Get them to have a look at the saddle fit too and if they say its ok get one of these:

His backs ok - he's just a four year old with some growing to do. Puts me off buying another saddle a bit as I know he will naturally change shape, but likewise I don't want to put extra strain on his back as he grows.

Can you use remedial padding 'til he evens up? Like the Nuumed half pad with pockets that you can ad shim pads to? Relatively cheap to do compared to buying a new saddle?

Have thought about padding but not sure if this would restrict the growth of the muscle over time. If he was fully grown I would be more inclined to do this I think.
