I vote against Al because it tends to gall/stick worse than steel.

Other than that I have no real strong opinion although I am partial hard
maple as the material of choice simply 'cuz it's easiest to sneak up on
the prefect fit...even the purchased steel runners are typically a
little sloppy...

'sneak up' is the key here.

I've read (and it's true for my tablesaw) that Delta slots are a tad
over 3/4". This makes using a piece of 3/4" Aluminum bar not so good
unless I use both miter slots and shift the bars together (or apart) to
rub on a single edge. Every aftermarket miter slot dodad I have gives me
grief. The bulldog featherboard works great, but I have to tighten the
snot out of it to get the expanding wedge to grip the miter slot tightly.

Using wood lets you get a perfect fit.

Incra (and others) make adjustable miter bars to solve this problem.

Those work very well for most applications.
But damn if they don't scratch the hell out of everything! :-p

;-)

Well, I don't slide it across the top. They're supposed to be in the
miter slot.

Haha! Seriously though, that's a great product.

I haven't actually used them, other than on my 1000HD.
