I've tried a bunch of bows, and for me at least the Vision Falcon is the best shooting recurve I have. Smooth draw, quiet, quick, and it just seems to shoot where I look as good as or better than any other recurve.
I can't help you on the aluminum arrow selection. I shoot Carbonwood 4000's and Gold Tip 55/75 out of mine. ((57# @ 29")
Is the one you are looking at used? If so, if the price is right it wouldn't cost much at all to try it. You could always resell it and recover your money. There is a good market for the Robertsons. But my guess is that you won't have to worry about that anyway.
