I like your females. The heifer is a looker. Any calving ease bull looks like it would work on her. Nice gal.
Both of the mature females have plenty of body. I can't tell alot about them in great detail. Haven't been able to figure if its my eyes, my computer screen, old age, quality of photo or all the above. the second cow looks long bodied and has some depth. Looks like she might have some shoulder. If those ladies (mature cows) don't have any calving issues then I would give them club bulls a shot. Now someone on here I think it was CAB promised to use Heat Waves full brother Red Wave. Bred by the same folks that bred Heat Wave. Maybe you could try him and tell me how he is workin? I used Shockwave so their is my contribution.
