The way I see it the puma is the best machine for the job and also the most versitile, if you only haul 2- 3 tons? with a machine that can take 4 i can see why you guys think it is expensiv.
K max 3 tons, 80 kts no pax.
Kamov 5 tons few pax if you compres them first.
Puma 3,8 tons 18 pax long range...
For me it is the puma that wins.
