Hi Marv,
Thanks for the links. The G3 Hyperions look the ones to have at this time. As you say not cheap, especially if you get the paperwork charge from the carrier that you don't choose

I was for going 5s to help with temps and the 20 min finals.
On the Caster I could get 18 mins but that was after concentrating hard not to be a nitro driver, blipping around the corners.
