Do you put the old wood up, or down? Old wood down would tend to cup
on the surface due to warpage, but old wood up can lead to shelling.
Quartersawn decking? Sounds expensive.

Thoughts?

Old wood up so the cup is on the bottom. This puts the
crown up and it will shed water. Otherwise the cup will
hold the water which is worse. I have both on my deck
as I bought milled boards with rounded edges and 3
grooves on the bottom and didn't have any choice in how
to lay them. I know better now.

Yeah - I agree. But I thought I read somewhere (Understanding Wood)
that they said you should put them the other way. Plus, some show on
HGTV had a couple of "expert" carpenters say you should put the old
wood down - so that it would shed water! I see a lot of bad or just
plain wrong woodworking/carpentry information on tv these days. DIY is
the worst.

You mean old wood down so the cup is on the bottom.
In other words, center of tree down
Or Quarter sawn, yikes.

Use a under the board fastening system and don't worry
about any of that. I used Deckmaster but there are others.
You will end up with a MUCH nicer looking deck that will
last a few years longer. Fastner failure is the biggest
cause of deck failure.

If you MUST fastnen from the top, use square drive
stainless steel screws.

Do the sqaures in the heads help the screws stay in better?

Nope. They're just less likely to cam out and make driving the screws
easier.

No..the square drive is for your benefit. They are MUCH easier
to drive. The stainless is for longevity.

Tried some square drive stainless deck screws here a while ago. No, didn't
cam out, just stripped in place.
