I guess really it is the similar deal as drum brake verses disc brake ~
Some lay claim that a drum brake is more efficient and not prone to locking ~ ( yet to see a lockheed brake lock !)
(And after riding a T120 with conical hubs ~ I was extremely impressed ~ in as much as "Ian " had fixed those Puppies well and truly !)
I am base my assessment on the view of others/ professionals that deal in these things ~ and much more acute than myself ~ and I am happy to fit the filter and change the oil and filter on a regular basis ~
The deal Works for me ~~
