I gotta admit, I "own" DRDF ever since that last little POP a few weeks ago and I never even looked into them (I hardly ever do down here in the cellar, LOL).
Anyway, great DD on your part; keep that up and you might just find a diamond in-the-ruff one day!
One more thing, hopefully that built up your confidence a little, go with your gut and post your work next time, all that can happen is discussion where everybody learns and that's a good thing.
(if you want, you can use mine for a sounding board)
