Hi Jack!
Take this for what it is worth.... I don't think you will find anyone who will let you fly front seat in a 8. But Go FLY with Alex Dedominicis or Mike Seager if you get the nod from one of these guys in a 6 you will be golden in the 8. I am a low time pilot with right around 300hrs now and before I flew my 8 I had around 125hrs in a 7GCBC. And maybe I am just a below average pilot but the 125hrs in the citabria was just not as good as 10 hrs with Alex in his 6. A light RV with a C/S prop is just not at all like a citabria as far as your mind keeping up with the plane.
Go fly with a good instructor in a RV (like Alex) and you will see what I mean. The RVs are amazing airplanes!!! My 8 is easier to land than the citabria... but it is a quicker more responsive airplane and you have to be mentally as quick as the RV.
Anyway I don't know much other than I LOVE MY RV!!!!!!
And you won't regret buying one, but take the time and money and fly with a experienced instructor it will be the BEST money you will spend.
All the best
P.S Dakota Queen is doing great!!! She is still fast pretty and best of all ....ALL MINE!!
