thanks again to all for your advice/input. I feel as though the combination of boat weight, bunks, and the different angles of the ramps I am always having to try something different. That's life I suppose.

I do power load when I can. however it seems that in order for it to self center I have to have quite a bit of the bunks out of the water Like Erie Eye suggested trying. The weight and friction of my boat on the bunks in this case makse it almost impossible to power on all the way to the roller. I then attach the winch and crank it as far I can. but then as Sherman said in his post, I have to back the trailer in a little bit at a time in order to lighten the load enough to winch it without pulling the bow eye through the boat!
Thanks again for helping a rookie boat owner. I've had the boat for 4 years now but only get to take it out 2 times a year it seems. so i still consider myself a rookie!
