Just a minor correction, being a party reduces SB gained from each kill. But, a party will kill more monsters faster, thus, producing a net gain in most situations.
HQ: +20% SB gained
Each melded materia: +20% SB gained

SB rate varies based on item level (iLVL) versus monster level. You must kill a monster with 15 iLVL of the item. The optimal SB rate will happen when the monster iLVL is 8 or 10 levels (seen both numbers) higher than the iLVL of item being bonded. Optimal bond rate is somewhere near

OP wanted to SB Patrician's Gear which is iLVL 50
Urth's Fount will work just fine but a must faster bonding would happen from running Brayflox's Longstop (Hard), Halatali (Hard) and The Lost City of Amdapor.
