I also found with the Angel GT that I easily got right to the edge of the tyre. They were good in the wet but still not as reassuring as I find with the PR3's. The PR3/4 has a "bigger" profile and I can never quite get to the edge even though I would say I was cornering faster than with the Angel GT. Currently running PR3 rear and PR4 (std) front that are absolutely fine together - my fronts last longer than the rears.
Even pegs down angles at Donington and still not off the rear or front tyre on PR4s and it defo sits higher
