Think you will find a 500D or E will bethe best as you are not carrying pax. It will blow the doors off the rest when it comes to agility performance and sheer fun. Due to its cruise of 130kts plus it is cheaper on fuel and component times compared to the rest ( 206 at 110 kts means you are using 20% more fuel and component times). 500 has no calender items like 206/enstrom straps. More importantly they are one if the few helicopters that hold their second hand value. The bills on a 120 when it comes up to module overhauls are eyewatering !!
