ppheli,
the helipad profile that you speak of for takeoff is really useful but the Max AUW is restricted so if you have any sort of fuel load the payload is poor.
I did some helipad profiles in an AS355 and with a reasonable bit of fuel, we were only 3 on board at max helipad weight.
On the north sea offshore, they never do helipad profiles for takeoff as it can cost about 1000kg of payload in a AS332L which makes them impractical and uneconomic.
