Swivel selection

[Zack]

I know that the "U" shaped swivels can interfere with movement when you change planes (say from a FSP to a hook). Is the problem the same with a chain-link swivel? If so, is the better option a plastic ball-hook swivel (unless I can find an old metal one)?

Exactly

some use and love the styles you mentioned, but most of us use the ball & hook...plastic is quieter and possibly a bit slower...i have both plastic and metal swivels installed on my platforms, and I have no preference between the two materials...

They each have their own advantages. The consensus has been leaning towards any ball/hook swivel except for the stamped sheet metal ones) for all around use, but they are noisier and slightly slower than the U shaped design.

In my opinion the chain link is the least desirable.

IMO, yes - it is the worst swivel for "adjusting" the rebound during plane changes. Sometimes it is very evident, and sometimes it is very subtle, depending on your ability to hit from all around the bag. Many of the more advanced linking changes involving the Three main double punches (FDP, RDP, SDP) can have 20 + direction changes and the chain link in the connection cannot adapt to them as easily as a ball. Not everyone will notice that until you can put either hand to any plane around the bag after any technique. Then it will drive you nuts.
