We always recommend seeking advice from a saddle fitter when selecting the most appropriate girthing option
Start with the straps through the sleeve and if the saddle remains stable when the horse is moving, put the girth straps through the neutral slots
If the saddle slips forward, the forward slots can be used
The back slots should be used if the saddle slips back
Only use the splayed option when further stability is required, and seek advice from your saddle fitter
