Here is what my old memory remembers about these bulls. May not be completely accurate so feel free to correct my ramblings.
Buck: Black Simmental that could sire big quarters, but sloppy fronts on some. moderate frame. Still useful.
Explosion: Mr. Tri Explosion? Red Maine bull from Rick Frye, calving ease and super calves both steers and heifers. I would still use this bull.
Shakedown: K&A sire
Streamliner: Power Plant's sire, larger frame
Reflector: DJ Reflector, good female sire. Sired some good steers in his day.
TC Dividend 963: Angus, good female sire, but some calves lacked muscle and were refined.
Payday: Sired by tidal wave, breeds similar to Power Plant.
Jolt: MCF sire, 3/4 maine with some simmental. Huge hip, birth weight might have been an issue, not sure.
Lovana: Old Ankony angus sire, won about every show he was entered in.
Polleroid: DMCC bull, great female sire, steers were ok.
Platinum: A Kroupa legend by power plant. I have semen and will use it on the right cow for maine angus x steers and heifers
Stilts: Old Maine, big but good females. Will upsize, lengthen and tighten.
PS Power Play: Old Penn State bull,
Stinger: Old Hullinger/Klingner shorthorn, TH?
