I bought a M14 and found that 14 chains didn't always stop the disc. I added 7 more chains and now it's as good as the permanent baskets on the courses.
I got 21 S-hooks and 7 pieces of chain each 20 links long. I attached one S-hook to the same points that the inner ring of chains are attached, the next hook 3 links along the chain to the outer ring between the existing chains and the third hook to the end of the chain and the bottom chain ring.
The basket cost $135.00 from Sun King Disc Sports (2 years ago) and the extra chains and hooks were $70.00 at Ace hardware.
