So, who did you send them to?
What do they charge?
Is there a better pattern than 'good'?
What is the optimum/top flow rate (or what would you get from a new one)?
Is there a viable home remedy for this, as opposed to sending them away to
be serviced?
How would this be worked into regular maintenance; in other words, is this
the kind of thing where you would have four extra on hand so that after x
miles you would swap in your four good spares, send the others off for
cleaning, and swap those'uns back in when x miles rolls around again?
(Assuming you couldn't readily do it at home.)

Inquiring minds wanna know... (or, at least mine does).

Cya,
Robert
