Ian,
For the record, I just wasn't sure you knew what your were talking about because as far back as I recall I have used the term or have heard it referred to as simply the TG, not the (T of G). Anyway to be honest I think your more of a book worm from your ramblings without much practical behind you, and my reasoning for your rib transfer is still holds true. By the way, I stated carbon black in the sun reaching those temperatures, you know the stuff we use as an UV barrier over composites prior to topcoat, not carbon fiber cloth. I also think Kieth would appreciate getting an honest educated opinion from those with some credibility, a track record, and something they can show to the unknowing if need be.
