rpdranc, I can't see that anyone addressed your question. I am only one season ahead of you and still a newb, but based on my searches last year, the vets on here would probably recommend that you prune your runted corot noir back to 3 buds and let them start over. My experience last year supported this.
One of your pics shows a vine where you layed the trunk down along your top wire to form half your cordon. I have seen posts on here were people recommended not doing that because that half of the cordon ends up dominating the one you will grow this year. It might look like you could take a little crop this year on that guy, but remember that the entire trunk and 1/2 cordon that you have is on 1 year old wood. It is essentially one long cane pruned cane. The most fruitful buds on that can are going to be 2-4 ft off the ground. The buds on your mini cordon probaby wont be all that fruitful
With those to factors in mind, you might want to consider pruning off those bent over trunks at the wire or few buds above, and grow equal strength shoots off that guy into cordons this year.
Generally speaking, don't try to keep any wood less than a pencil thickness in diameter.
