I bought my hooks from Tuck n Tow. You can actally fit 1/4, 5/16, or 3/8 chain in them. I have only used 1/4 or 5/16 chain so far. I have only lifted about 700 pounds, and never used all 5 hooks at once. But, like TripleR said, I use 2 to 4 hooks at a time to loop or balance out load. I normally use them to load an extra implement in the back of my bed (box blade, pulverizer, etc) or to move my sub frame and snow blade around if I don't want to mount it to tractor. With the heavy duty bucket, there was no need to weld a reinforcing pad. You may want to consider the reinforcment pad between the hook and the bucket with the standard duty bucket. Philip.
