What are other rods like the Orochi XX Leviathan that's 8ft or longer, with a detachable handle, and can handle swimbaits up to 5~6oz.

You might want to contact LDC (Low Down Customs), they may have a telescoping swimbait rod to meet your needs or can make it.

Spiralite has an 8'3" & an 8'6" telescoping in their Maverick series.

what's a good one for throwing swimbaits 2-5oz? Iv seen all the megabass, deps and majorcraft ones but want to see what else is out there. doesnt have to be over 8', but close to it.

The megabass white python is my fishing partners favorite 7'6" up to 4 oz I believe.  They have a new model totally diffrent.  His is a slant bridge.

Does or did Gan Craft have an 8' model with removable handle?

Yes they have 3. 7'6", 7'10" and 8'. But they are all way too expensive and hard to find
