IMO, with amunition avalability a big consideration (which it is) ,I would say a 470NE at around 10lbs is about ideal.
If amunition was not a problem and the Zambezi Jesse was one of your main stomping grounds, a 500NE at 10.5LBS would be hard to beat.
PS; I am soon changing from my 470NE to a lighter all round 450/400J.
