Exo Cage tubing size?

[WTF]

In my preliminary planning for an exo-cage, I'm trying to figure out what size tubing to use. I'm thinking about either 1.25 or 1.5 . Weight is a consideration, as well as appearance. I'm thinking 1.75 or 2.0 would look overly bulky as well as being heavier than alternatives.

Upon searching it seems that almost nobody lists the tube size used for exo's. C-rok doesn't list the size of their exo on the site as well.

Any pictures of exo's along with the size tubing it is constructed with would be awesome.

Before anyone says anything, Interior cages are pretty much ruled out, because i'm 6'6" and have ridden in several caged xj's and left those rides with minor concusions and lumps on my head.
I am entertaining the thought of some cross-bracing at the dash and B pillar that will tie into the exo through the body.

Can anybody give me a link to the specs for hrew, dom and sch 40? I've seen it before in various threads but can't find it tonight (perhaps the post new years day-long hangover is giving me a mental block on that...).

thanks.

1.5 looks nice, i wouldnt go any smaller for strength issues

We use 1.75x.120 for most of the members. The radiator and cowl guards are 1.5x.120, as well as the B pillars on the 4 door kit.

im just starting my cage, its kind of an interal/exo cage, the main parts of the cage, which are actually going to be welded into the sheetmetal are going to be 2", the exo parts are going to be 1.5"

My exo on my MJ has 2"x.250 Dom rocker bars, and everything else is 1.75x.120 except for the windshield bars. They are 1.5x.120. Here is a link to mine http://independent4x.com/generic67.html I know ppl are going to say my cage needs more bracing, or w/e, but remember it isnt done yet
