Ibanez Edge series trem arm question

[odibrom]

(...)
I expect the adjustments that I made will last quite a while with my playing being spaced out between multiple guitars.

This is the main reason the bushings on my guitars last ong enough for me not to worry about getting the "magic arm" thing. I'm not an abuser and specially I'm not rotating the arm whenever I want to move it, so the bushings or washers last quite long... and I still have a small collection of brand new ones ready to be installed whenever needed. An they're way cheaper than the magic arm thingy...
