Leon. Have you ever had a look at the Cadex nailers? They're a pin
nailer that shoots a "slightly headed pin". The key benefit to them is
the increased holding power.

Now, I'm wondering how much of a difference there is between the foot
print of a regular pinner and one of these "slightly headed pins"?

I've got to say, every time I'm in the market for something new, the
internet can be a curse as well as a blessing. There's so many options
for stuff these days that it's often a pain to pick something.
