I got rid of the stock tool pouch because it was too small and my boot would always catch it while getting on the bike. I'm a big fan of leaving the luggage rack on because of the handles for pulling the bike out of a mudhole and you can mount your own toolbag on the rack. I'm using the Moose Fendermount Tool Pack. I don't have it mounted permanently, but rather weave the pack's straps through the frame of the rack and it stays in place. No worries about losing the tool pack on a rough trail because a bungee failed. The pack holds all the tools I need for any trail repairs.
