I ended up ordering some new PBC hooks for my Weber hanger and then ordered a GDS hanger. I didn't open the PBC hooks. Will try next time I use the Weber hanger, although I expect the unused GDS hanger is going to be the only one I use. I used the Weber for the first time; I didn't like how the bars slide back and forth. Am looking fwd to the fixed bars of the GDS.
I think the PBC hooks would work better with the Weber hanger; the crossbar hook has a nice radius that would fit nicely and easily over the weber round bar.
OTOH, the GDS with the sharper bend seem to work fine, I expect they will work better with the rod style GDS hanger.
The PBC are a little longer in both directions, but the angle of the meat hook looks similar.
The GDS hooks end up costing quite a bit more when purchased direct. The GDS shipping is $20 more to my postcode. They are available elsewhere for a bigger price, but cheaper shipping. The PBC has 4 and 8 packs with friee shipping over $25. They've got some other nice hanging accessories, that make it easy to get above $25. I picked up some vertical skewers. They also have nice looking baskets and corn and dog holders.

My first WSM 22" and first hanging cook with the Weber hanger and GDS hooks.
