spur help

[ClassicG&T]

i currently use the little 2cm "jabby" spurs as horse is very behind the leg and needs a bit of a reminder when schooling and particularly hacking.
But they are too sharp when schooling as, like i say they are jabby and they are more for his napping out hacking.

what spurs would you recommend for schooling, just as a little back-up but not a dig in the side, if you get what i mean?
maybe the metal ball rolling one, or the rubber roller ball?

you could always get ones with the changeable ends but i like my round ended spurs... i dont like the rubber ones but the ball ones are alright too

None tbh. Spurs are for precise aids not to get a horse going forwards.
