Convalco Forstners: alignment?

Greetings,
Someone here mentioned Connecticut Valley's Forstners a while back. I
looked them over and am convinced that they are the ones to buy. I got a
$7 chiwanese set to practice sharpening. The lack of a center brad in the
Convalco model is appealing.

When using a Forstner drill which lacks a center brad, do you
locate the work using a center-finder bit? That seems a tedious method for
multiple holes. Do you mark the layout with lines tangential to the
circumference, instead of marking the center?

When using a forstner bit to drill out for cabinet door hardware, I use
a jig with location marks on it that is literally a piece of plywood
with the hole drilled in to be the actual guide.

That way I never miss as I am aligning the hole to be drilled over a
hole that has been made to the correct size. No "oops" on a finished
piece of small corrections.

The above show how to locate the center without the center tip. I haven't
seen one without a center brad until now with the Convalco.

Thanks. A template marked as shown in the link, then bored, will allow
quick marking of the circumference on the work.
