Chain Suck, any ideas?

Any ideas on how to eliminate?
I've heard many times that Brodies are notorious for chain suck and it's driving me crazy. Any time it gets bumpy (and since I ride in the Rockies, all the time) my chain ends up jammed. I've replaced the whole drive train, new chain, crankset and rings, new rear cassette and the chain is the right length.
Please offer any suggestions you may have, other than this one issue I like the way the bike rides and really don't want to have to cut into my ski gear fund for a new bike.

Make sure your chainline is not messed up. Look on the website or send brodie an e-mail to see if your BB is the right length. Are you running a triple or a double and bashgaurd? You need a different chain length for either one or else a median if you switch back and forth.
I am assuming it is going off the front not in the cassette. Make sure your crank is still tight. If the bolt loosens off and the cranks are not as secure as normal then the chaincan get sucked in every now and then.
Those are my $0.02, it may or may not help.

Oarhead,
Thanks for the reply. It's all brand new and tight (gave everything a check on the trail yesterday just in case) and the bottom bracket came from a Brodie dealer. Triple chain ring, don't switch it ever and the chain is brand new and properly sized. I worked in a shop for a few years, have been riding MTB's since the eighties and raced bmx as a kid, so I'm pretty comfortable that everything is set-up properly.
Just hoping that someone might've tried or done something to help with this.

just check the chain line, but it sounds like that should be OK. Even if it is a new drive train, and other the chain line might still be out. If you have the bike in LL I can check it for you with tools to see if it needs spacing out.

Does the suck happen in all 3 rings in the F or just the smallest?

9 speed chain, rings and cassette?

again I assume so, but worth checking.

Also changing brands (Sram chain, Raceface rings and XT cassette never help) Kepp it all in the familly
