Hi there in Gray!
Ken's product seems to have really a great alternative from welded one.
Bigger loader (big Cat loader, for exemple) has only one cylinder for lifting the bucket, it's stronger. Two cylinders might be nicer to look at, but they have to be working in pairs... No off balanced lifting, if one cylinder gets kink, most of the hydraulic flow will be shift to the other cylinder: disaster is close... If you lift a heavy object with the side of the bucket, no so good... Most experience tractor mechanic will advise you to install your hook right in the middle. 5/16 grade 70 (work load limit) will lift up to 4700lbs.
Good luck with your installation!
