I am sure wildkat makes a good grapple,heard alot of good things about them on here. I have personal expierance with Deere grapples, there darn good. I used a 72" most of the summer on a ditch bank we cleaned the timber off of with the excavator. That always makes a mess. I think your tractor is in the 50 to 60 horsepower range? There is alot of debate on width. I think I would stay with a 48" though. But you could probly get by with a 60". A guy just needs to use common sense and good judgement. I am going with a 48" on mine,but it is a 4200. A bit smaller than yours.
