I also think it's important to just go ahead and jump the gun. Before your rig is even built you tend to almost over research and worry about every little thing. I think go ahead and even just get a 1 card rig going. It's always easier to learn by doing verse reading the endless knowledge out there.
i'm very new to this stuff but since actually jumping in and getting some 'skin in the game' I'm learning way faster, all the stuff I'd read about ad nauseum but didn't know how I would respond come game time. I'm not sure how many times I may 'learn' some of these lessons lol
