I'm trying to sort out what's necessary what's not on my first atv and could use a little help. I was sure to buy a Griz 550 until I wandered into a Polaris dealer over the weekend, I wanted to look at the ACE and a 570. I was impressed with the 570 except that you can only get EBS on the camo model and no ADC was available on any 570. I'd have to move up to the 550 if I want ADC. I'm hunting in a steep part of a buddies property, steep enough that it was a real pain trying to descend in the dark, lots of mud and rocks to boot. Climbing out was no joy either. I'm thinking ADC is almost a necessity but I'd like to hear opinions. Is moving up to a 550 worth the extra $$$ just for ADC? I've heard there are issues with the frames in comparison to the value line. Suspension and engine hp isn't really a concern to me since this is more a slow work than fast play vehicle, at least for now.
