Hi Arthur,
Thanks for that informed view. As I said I have had nothing to do with the 2 stroke engines and its good to get the view of people with your experience especially for someone like me who is just starting out in this hobby. As you said there is alot of pros & cons to both 912 & the 582 but after hearing what you had to say and doing abit of research myself I am starting to lean more to the 912, simply for the bettter load carrying and looking at a comparison of cost of tbo up to 1200hr the 582 is about 8k more to maintain, this comparison also includes fuel burnt aswell & as you also said value money ie: performance, resale.
Cheers Tim
