tia ooh yes those are fun! Since KNNs need patterns to be KNNs, I'd think if you breed them down short, any that skip the appy would end up SH, so it'd be easy to do both lol
tia y'know same honestly xD after almost 2 years, i've finally settled on AD TBs and SH, jumping Xs, dressage WBs, and up until yesterday I did XC AAs xD
I also agree with KPH about only having AD- trained riders for everything. It saves a lot of time and money haha. I do have SD riders for futurity but they're only level 1-2 so they're fairly cheap, and then they go back into the AD population after they're finished
