GRP Stallion FS Numero Uno

Hi Everyone! I’m hoping to breed my WB mare to the GRP stallion FS Numero Uno this year. Just curious if anyone has used him? It sounds like his offspring have good minds, but I’d also love to hear anyone’s experience w his offspring, temperament is my number one thing (I have a Jazz mare I’m hoping to bring the temperament down on). I’m also curious about his frozen semen quality- I can’t seem to find any info on his frozen conception rate. Any info on him is appreciated! Thank you!
