Hi Rom,
For a while I thought you were just making a joke about literally a rat cage - then I read up on it and now feel like a noob

Yes I would ideally like to stay away from that design if I can, don't like the idea of everything sitting on 4 M20 bolts or the like. I'm going to start a thread soon on my pier build and I'm leaning towards having small grub screws/shims for fine adjustment at the base.
Troy,
You made me dig through my Uni books again

I'd be mounting a NEQ6 + RC8, conservatively estimating 50Kgs to be the absolute highest I'd ever go. I figured it wouldn't be as stiff as the 230mm CHS but it will definitely do the trick for me. And based on people's opinion so far, I will probably have no rat cage at all
