Lofting lunacy

Evening all!

Can someone help me on a query I have about lofted surfaces please...

I'm trying to loft a mobius band and some variations but its the loft issue I want to figure out even if there is a better way of drawing mobes.

When you loft through a set of curves the surface seems to get puled according to the direction of the curve. So when I draw a closed loft through lines, the surface gets flipped back to meet the first line in the list and looks like this:

So to get around this, instead of a closed loft, I draw a line in the same place as the first line in the list, only in the opposite direction... all good, but a bit messy!...

However, I want to loft different shapes around my mobius and the reslting lofted surface doesn't look so easy to fix with a "bodged on the end" line or two!...

I understand why this is happening (I think) and wonder if there is a neat way in GH to deal with this as I often encounter problems like this where I end up needing to align things in a list but not knowing how to do it.

Am I missing something here?
