I have a 6.2 Curado K that I plan on using as my deep crank reel. I am toying with the idea of putting a bigger handle on it but one that is reasonably priced and not a nightmare to get on. Anyone have some suggestions?

You can get a 96mm handle shank directly from Shimano and just use your knobs off the Curado. I have done this with many of my Shimano's. I always replace the bushings with bearings as well. Depending if you want a black or silver handle you can choose from the Chronarch MGL XG or Met MGL XG handle shanks. I always order the handle retainer and screw as well since they are just like a dollar each.
