I would find it best to get as many of big the root crowns out with the rake on your dozer. I would spray any new shoots with Crossbow once they are around 18" to 24" long and leave them for 3 weeks or so. I would then brush hog and repeat once any new shoots get to the 18" to 24" range again. Every time you should have fewer shoots. Some will be from dormant seed waiting to grow. Some will be from root fragments and some will be from missed root crowns. The ones from the crowns are the hardest to kill since there is so much mass to the root. The ones from the fragments and seed should be easier to kill with the Crossbow since there is less root mass. Mix the Crossbow at the recommended concentration and apply it with surficant so it sticks. The reason I like 18" to 24" length is so there is enough surface area for the herbicide to adhear to and transport itself to the root. Closer to the root is better. I would burn the berry canes over the previous growth area so that you kill any roots there (might as well). I would prepare the soil and seed with grass as soon as possible to help choke out the berries. Crossbow does not kill grass. Keep us posted please. Good luck, you CAN do it. It will take a few years, then forever maintenance spraying, but even that will go down.
During my break from the driveway (and deciding how to proceed) I cleared out blackberries in an opening in the trees. It's about the size of a football field and will be the future food plot for elk and deer (included elk rub picture on edge of this area). I used the dozer on this part pretty aggressively and seen a lot of root balls 8-14" around but it took awhile to get everything smoothed out and didn't care for the huge piles of vines/dirt and the extra time it took to smooth it out with the blade so when I got to the 20acre field I decided just to brush hog it down. The coyote sure did enjoy all the field mice I was dispersing but I don't think the deer liked losing their bedding area. I couldn't brush hog the food plot because of all the garbage so each area it seems I will have to use different methods. I do plan on following your advice with the crossbow.
