I want to get a Dobyns 765 for dt10s, dt16s, 5XDs, and 6XDs. I'm stuck between the graphite and the glass and I don't know which is a better option.

Do you prefer glass or graphite rods? That alone should make your decision for you. 

 

I personally prefer graphite and I own the 765cb and it's my favorite DT10 rod. I wouldn't throw a DT16 or 6xd with it though. I'd want something a little bit more powerful for those.

805cb is the best all around medium and deep diving crank rod imo. 

I prefer graphite as well.  I like the gains in detecting what I'm running my bait through.  I don't feel is as well with glass.

Can it still cast lighter crankbaits like dt10s easily or is it too much?

I don't use the DT series but I throw 5xds, 6xds and even 3/4oz traps on it. It's not a broomstick at all. Also handles the 10xd really well. As another option, I'll throw the irod Genesis II Fred's Crank Launcher in the mix. Really love this rod. It has a really nice tip and can also handle just about medium or deep crank.
