Looking for an AI percentage Chi bull for replacement heifers

Looking for an AI percentage Chi bull that will produce replacement heifers that milk good and have big bone/ butt.  Would also like 80 pounds or less BW and clean of all genetic problems such as PHA, TH.  Dame is commercial (Simbra/Simmental and always produces a great calf, thinking about flushing her. Do you have suggestions?

CTR Success, Bullbarn .com & I've been watching JSC Momentum,40% chi bull

I believe CTR Success is exactly what you may be looking for. Listening to numerous breeders, he is as fault free as they make one. Calving ease, temperment is great, and first calf heifers milk and raise calves as well as most mature cows. You don't see many for sale which also says alot. Danner's in Nebraska uses him and ZNT here on Steer Planet loves what he does in making good replacements. He seems to work well on OCC genetics and Maines from my experience.

Sorry CAB. I was writing when you were posting.
