Locknut, antifade locknut, etc

[Justin R]

I guess since I haven't posted in a while I can't search the forums, so here's my question. I have a 1987 trx 250r that I'm rebuilding. I found the stock axle locknut or whatever it's called is a huge pain. I need 2 giant crescent wrenches to remove it. I have found some antifade locknuts from rpm and some different locknuts from lsr and other places that look like you can tighten them with a hex key. Are these newer locknuts used to replace the big bulky stock ones? If so does anyone recommend a certain type? The RPM looks decent. It doesn't cost a fortune.

Thanks
