Any northern New Mexico unit has good bulls. There are big bulls in all the units, just not like down in the Gila! You will find 330 Class Bulls in the Northern Units you just have to hunt a little harder. Unit 6c is a good unit you have to hunt fence lines that border the Valle Caldera but don't dare cross those fences! The Proc. says there is low elk #'s in this unit, but that ain't true! for this reason you have a good chance at drawing a tag! It's just such a big unit you have to learn where there at. A problem that archers have in most northern units is there are guys that like to use there Bow Magnums!!! units that are good to hunt is 51, 52, 6a, 6c, 44/45. I know these Units very well and you can kill a good Calibur Bull you have to put in your time. Of course your Unit 16's and 15, 13, 34, 12, 17, 13 are Awesome units, But good luck drawing one!!!
