Some versions of this shelter come with one black 7 ¼” loop (7 ¼ B2) connected to each gross grain ribbon stake point (B1). You need two 7 ¼ loops connected to the Meg for setup flexibility. Also make up four 23 ½ gold reflective lines (23 ½ G2) for use in warm weather when you want head room but don’t keep them connected to the tent. Assuming your Mega comes with the B1 loop, add a second gold/reflective 7 ¼” loop (7 ¼ G1) to each 7 ¼ B2 loop that is, in turn, connected to the B1 stake connection points. Then use the following technique to facilitate the Mega/Bug setup: (After posting I noticed that these table didn't format with the horizontal spacing I had in it. The x for the 5'6" height option should be under B1, the x for the 5'10" height option should be under B2, the x for the 6'2" option should be under G1, and the x for the 7'3" option should be under G2.

0. Locate an 8' square flat clear area. The Mid is (86x86 = 51.4 ft2)
1. Stake out four corners of the Mid using the loops appropriate for the pole or paddle height and inline with the corner seams. Insure the buckle on the door is kept snapped.
2. Spread out the Bug inside Mid to and fasten bungees & toggles
3 .Set pole to proper height and insert into Mid / Bug
5. Add the Mid center stakes and fasten to Mid & Bug
6. Adjust Bug floor toggles if necessary (tight-storm or loose-vent)
For maximum interior room set the Meg/Bug up using the 5’ 10” loop settings. Then use two 220 cm slanted poles (paddles, skis, etc) between the Meg and Bug to provide support without using a center pole. Note that the Bug needs to be connected to the single pole or double pole frame. I use kayak paddles when paddling and I cut some downed limbs to these lengths, at my destination, if backpacking. Optionally you could carry two poles with you.
I have used a Mega / Bug in Alaska for two multi-month expeditions plus numerous shorter trips in other areas. For extremely windy weather I use, the 5’ 6” low height pitch option, supplemental guy lines, and general purpose size Grip Clips, http://www.shelter-systems.com/gripclips/index.html to dramatically improve the Mega stability. Place the Grip Clips midway up on the windward side of the Mega when needed.
With the above set up options, the answers to your questions are as follows:
How well does the Megamid take winds? At 5’6” height with supplemental guys it is bombproof
Does it have many guy lines or guy points? No guys come with the Meg. You have to make up your own as mentioned above. I use four.
Is it really a four person tent, or will the people on the outside get damp or have practically no real room? It is a four person tent only in the configuration that doesn’t use a center pole.
Is the mega light fabric actually stronger than the mid, like what Black Diamond claims?
It is stronger but it is not fire retardant. I suggest the Mid rather than the light if you are going to be cooking in it.
What are these tents like with snow loading? The roof pitch is 30 degrees which prevents any loading on the tent.
How strong are the carbon fiber poles that come with the light? Is it better just to use the alloy pole in bad conditions? The carbon fiber pole is of large diameter and consequently very strong. I use the segmented variable height aluminum pole that came with the Mid.
