I'm building a workbench that I originally designed to have a series of
3/4" x 3/4" bench dogs. I'm about to cut the dogs, but I came across
some 8-1/8" bench hold down clamps:

So, which should I go with? The dogs or the clamps?

The workbench will have no specific mission, just a general workbench.
The dogs are 3/4" square and the clamps are 3/4" diameter.

Thanks.
