wood pipes, are they only for old men and tobacco?

I would say those two are probably better for tobacco. They look like the traditional tobacco pipe that has a really deep bowl. That kind is hard to fit with a screen, and hard to pack a normal sized bowl. Also, it looks like those two are used, so they have already absorbed some pipe tobacco resin, which would be kind of harsh to fully inhale.

The wood pipe I have is a lot smaller than the ones you are looking at.

I don't really like wooden tobacco pipes for weed, just because the bowl is huge. But a friend of mine had a cool wooden weed pipe, with tie dye colors and a cap for the bowl that had a shroom engraved on it. That pipe was awesome.

im also thinking about smokin green hash in it with tobacco and regular weed

i like wood pipes but then i guess im an old guy now.
back when i first started you used to be abe to buy what was called a peanut.shaped like a peanut and cost about $2.used to keep basket full on the counter of the local head shop. they were more used as drop peices and had a tendancy to burn thru the bottom in a short time but in a pinch you couldnt beat one

differant woods will give a differant flavour also.
