As per the title really.
I'm going to be building up a Stumpjumper for XC shortly and will be cannibalising parts from the dead hardtail.
I want to upgrade the crappy Hayes HFX9 front but want to keep costs down.
Avid Code 5s are dirt cheap on CRC at the moment but they're a bit too heavy for an XC build.
On my DH bike I have some original (2 pot) Saints which I was thinking of bunging on the XC bike as they're not too weighty, then bunging the Code 5s on the DH bike instead.
