They will be perfect and give the fastest recycle times especially with the 5th battery. The only thing to watch is self discharge if you don't use them for long periods. The Sanyo Eneloops are very good if you want to leave a set of rechargeables in the flash for long periods without using them, but they are no match for freshly charged 2600s as you have.

Not sure about the 9000 printer but with inkjets its a balance and again depends how often you use them.
