I've got some news I wanted to share. Ed Skorepa sent me a bunch of carbon canisters to play with on the OS33, DLE35RA and DLE55. As I develop findings, I will post here and elsewhere as appropriate.

I've been able to tone down the pipe jump at 4K, however have not been able to eliminate it. Ed said that the canister eliminates the jump. Of course it's the dead of winter so developments will be slow at first. Doesn't stop me from doing some bench work tho....
