what model of stubben saddle can be used as a show saddle?

[Jennypenny]

As in the title, what models/types of Stubben saddles are used as a show/wh type saddle if any

 

[custard]

I've seen people using the Tristan dressage I think it was called but personally don't like stubben saddles. I think you can get away with using a dressage saddle to a point so long as it's not too bulky with knee rolls. trouble is a lot of judges can't cope with the straightness of them

The Romanus works quite well, straighter cut but not too 'dressagey'
