I don't own any DX, only Champion series so I cannot speak to that. I use the champs for moving baits exclusively. I will say that the orochi is more sensitive than the champs. I do not find the handle to be too long at all, but of course these things come down to personal preference. If I was in your shoes, and planned to use the rod for jerkbaits 75% of the time or more, I may save the 50 bucks and get the champion.. however, if you are going to throw the tubes and other plastics quite a bit- I would be all over the orochi for the sensitivity factor.
Also, not sure if cosmetics matter to you- but the orochi is a very attractive stick.
Best of luck on your decision- I know how these types of decisions can drive you nuts!
