Mids are mids. With a little practice they are easy to pitch.

The bottom sides of my ’80s Chouinard pyramid are over 7′ long.
Here are some thoughts. Keep in mind that high desert winds are not uncommon for me, so I am not looking for a “nice looking pitch,” but a pitch that will stay secure in high wind. A pitch that stays secure will also look nice.
So here’s what I do, and it is just my opinion.
First you have to lay the shelter out on the ground and get everything symmetrical, e.g, “square” the corners. Leave the door zipper closed if you have one. Now loosely insert your corner stakes with enough slack for adjustment… the amount of slack will depend if you want a higher pitch for ventilation or want it close to the ground.
Now insert your center pole. Get inside and tension the pole tight. Unzip the door and exit, then close the zipper.
Tension the corner stakes — tight! You need lots of tension. You may have to reposition a stake — it happens sometimes.
Now stake out all the guylines — all of them! Â Tighten, tighten, tighten.
You need a STURDY center pole. I don’t use trekking poles. Usually I bring .600″ carbon poles by Ruta Locura. Sometimes I bring a jack, sometimes not. With silnylon, jacks or adjustable trekking poles are best because the material has a tendency to stretch during the night, and usually cranking the height a bit takes care of most slack.
Stakes: There is a lot of tension on the stakes, especially the corners. Use strong stakes… not skinny shepherd stakes. Normally I use 9″ Easton stakes on the corners and MSR Groundhogs on the rest.
LineLocs: Yes, I use these and they add a tiny bit of weight. But I can really pull on these to get LOTS of tension on the guylines.
Guyline diameter: I switched out all my thinner guylines to 3mm to fit in my LineLoc 3 tensioners. Again, I cannot stress how important lots of tension is. And with lots of tension you need sturdy stakes, guys, and pole. I found thinner guys, even 2.5mm would slip a tiny bit under tension over a period of time.
Cuben is harder than silnylon to get a perfect pitch  because the material doesn’t stretch. The key with Cuben is to follow the steps I’ve outlined, especially laying out the shelter on the ground and getting the corners “square.”
I’ve never owned an inner, so I can’t comment on that.
Here’s a couple links to my blog where I discuss a lot of these points (poles, guys, stakes, etc).
