Original USA 525Mags are all very fast, running correctly,but still controlable.Couple drops red rocket fuel or similar oil takes the edge off them on normal stainless bearings.Personally think putting clean ceramics in is a mistake be far too fast.
Want to speed one up and still have the useable advantage of the slidey mag brake, take a magnet out the carrier.Nice to see you got the right result in the end,a good choice solid reliable reel,used them since they first come out.
