Beton, taking nothing away from your idea it may well work. But just have to say something about that 20% better on BF, er, that should be ****. i.e. the greater the price range the larger % difference, conversly as you go down in price so the advantage disappears to a negative.

I have done extensive comparisons, and backing Bob, TF, best tote/sp all beat BF HANDS DOWN, by as much as 10% (backing favs that is)
