Hopefully I can overcome the 'big nose' issue with > enough brute force ;-) I think it was Enzo who said: "Aerodynamics are for men who do not know how to build engines.."

The temp report is good - means your wing is working evenly all other things being equal. Look, like I said - I haven't strapped on a five point in so long my tackle has finally descended - however I would be easing into 150mph and beyond very slowly over a season myself. The great problem with crisp aerodynamics is that they work just as well off the pavement as they do on. Not trying to be a wet blanket or anything - I think 170+ is completely doable and the right way to go - but they sux huge if it gets off the pavement.
