Hey man, fantasy wise I'd say this is the way to go for now
My reasoning: Hall is probably the most offensively talented of the group, and he will be playing in young edmonton for years to come with loads of offensive talent and should be putting up great numbers.
Benn is next because he's consistently putting up points for the last 2 years and plays on the first line (usually) of a very decent dallas team.
Kane and Landeskog are very similar players fantasy wise- they both play on mediocre teams, both get a fair amount of points, but it's not quite a PPG, have lots of shots and a fair amount of PIM. They both also get a lot of hits, but your league doesn't count those so their value is slightly diminished.
Duchene is the biggest unknown, but for now, he's the low man on the totem pole. He is yet unproven and has greatly regressed from his breakout year of 67 pts, though he's starting to put up pts so far this year. I think he'll be good down the line, but for now is the biggest risk to keep.
