If you ask the biologists who over see these areas they'll tell you genetically they're the same deer. Only difference is, 90 is managed for older age class deer. Having said that, they hardly gave out any tags for 89 last season because the numbers have tanked. 90 wasn't much better and its gonna take several years to build up herd numbers and those older age class bucks. If I was had a bunch of points, I'd be hanging onto them for another 2 - 3 more years before I considered either area...
