Shimano handle assembly compatibility

[TexasRig88]

Hello all please help!

Id like to upgrade my handles for all my shimano reels (I have the lower end models), but I’d like to stay with “factory” parts. Which handle assembly are compatible with each other? Will the metanium mgl handle fit with a curado 200k? How about a slx?  Are you able to add bearings to the handles? Any and all valid info will be more than appreciated!

Thanks,

They're all compatible with each other. Bigger reels like Tranx are the exception because of an 8mm driveshaft vs 7 for the others. I don't see much difference in Shimano handles now across the price spectrum except for bearing count.
