To be honest I would not really class the Vertigo as a playboat by modern standards, it is seriously old school and quite hard work to get that many tricks out of it, that said when you do get cartwheels, blunts etc. down in a Vertigo you will find them incredibly easy in a modern boat.
As a river runner up to grade 3, it is ideal, fast, manoeuvrable and pretty forgiving and at 95kg (which is closer to 15 stone by the way) you will be right at the top of the weight range for it but should be just about ok, the only issue I can see is how comfortable you would be in it at 6'6" the answer to which I have no idea about, it feels like there is a warehouse of space in there to me but I am only 5'11"
