Almost anything can be stick welded and made to look good it's just a little harder to do a pretty looking job. If your a fairly good welder go ahead and stick it. It might need to be touched up lightly with a grinder to look perfect but there is a hell of a lot of pipeline's and boiler tubes,etc,etc. that have been stick welded. Just need to practice on the size and thickness tube that you'll be useing before you start. Mig is easier, faster, less fire down your sleeve that's all and with a tig you can go over the weld a second time to make it look better if need be. Stick it if you got em . If you do buy a new or used mig,you'll really like it and use it for welding things you never though about welding before...Good luck with your build which ever way you go...
