I put the most weight on the vs, and like others have said, vsR being more important.
Control and Eye I weigh equally. Sure, you can have great success with an 80 contact, 30 eye guy...but I think you can have the same success with a 30 contact, 80 eye guy. The first one will get called out on strikes a lot, but put the ball in play and rarely walk...the second will swing and miss a lot but walk more.
Power is the biggest modifier for me of how I evaluate a guy. Someone with little to no power, I am going to want huge numbers everywhere else, and probably either great speed/baserunning, or to be a Gold Glove shortstop type. Someone with huge power, I will let all other numbers go lower. I wouldnt normally play a guy with 40 contact, 45/50 splits and 70 eye....but add in 100 power and you are looking at a 40+ home run threat.
