Dave,
I’ve had my 620 for a year now and absolutely love it. A couple of things to keep in mind. One, stay away from the full glass windshield unless you plan on doing the “Sunday drive” thing. My partners 620 is proof of that. I have the tall individual pods which work great for blocking wind, rain and bugs. The low cuts, in my opinion, are NOT the way to go. It’s like a low cut windsheild on a snowmobile, they look cool but serve on purpose.
Second, if you plan on doing a lot of back-trolling, the counsel 620 would not be a very good choice as it does not have much for splash protection to prevent 3’+ waves from coming over the back. I would like to hear what other 620 owners have to say about this. My 620 does have a 6″ jackplate which seems to make the rear end of my boat ride about 1″ lower than normal, but I don’t think 1″ should make that big of deal.
I personal to not backtroll that much so that did not concern me. The 620, however, is a trolling machine, and that is the reason I bought one.
I forgot to mention one bad thing about the tall pod windshields. They will snap in half when 100 gallons of water hits them from spearing a wave. . . . ouch.
Good luck Dave on your Ranger purchase.
