Simmental Bulls Input Requested

Have any of you all had any experience with the following bulls, and how did you like the calves and retained heifers.

Kappes Direct Force K206
Triple C EL Ponderosa Rey
SJ Thorne
TNT Jumpstart  R238

I have used these bulls so I know how they have worked for us but was interested in others comments about the calves. 

Current Cleanup bull is out of Triple C EL Pnderosa Rey and a Nichols Legacy G151 cow.  Most likely going to buy back an SJ Thorne son out of an SAS/ASF ALL Star x Nichols Legacy G151 cow to use as a cleanup bull.

Only one I can comment on is Jumpstart. I think he is way under rated. We have used 200+ units. Mostly on high % angus heifers. Calve easy and they take off. Maybe a tick smaller framed than I like but they go on to be some great calf raisers.

I agree they grow really well.  How have the heifers turned out as far as temperament?  The ones I have seem to be just a little nervous, not too bad but just enough I have been cautious about using him again.

only one I can comment on is Rey.....
his daughters in our herd are second to none; they are in their prime now.
I have used Powerdrive on several to make linebred Powerdrive bulls which we are using
in herd.

they are nice, moderate cows; deep bodied, milk good....

I've been around a lot of Jumpstarts as virgin heifers never noticed anything. Our Jumpstart was easy to handle and the steer calves I've had here always have been too.
