After constantly having to be there to make sure the filament was feeding and not catching because the 5lb spool was too heavy; I decided to print a couple of Ultimachine Spool Spacers.
The spacer uses a 608 bearing, if you upgraded your H-1 idlers, you probably have a few extra lying around.
I have to now figure out how to attach the spool to the machine
