White-Striped Tallit: Beit Yosef, Malchut, Prima A.A., Hamefoar

The following is a series of questions and answers from a customer who bought a black-striped tallit from us in the past, and now wants a white-striped tallit for Shabbat. Since the distinctions from one white-on-white tallit to the next are subtle, I felt his insightful questions are worth posting.

Does the Malchut Tallit have a weave similar to the "box" or "waffle" weave found in Hamefoar, or more like that found in the Beit Yosef Talit?
The Malchut Tallit is very similar to HaMefoar.
 
Is the color of the Malchut more white, or more yellow/cream like the Beit Yosef Talit?
Both are very slightly off-white.
 
Are the stripes in the Malchut Tallit flat or shiny?
Matte, not shiny. The Prima A.A. and Hamefoar have shiny stripes.
 
I don't see an option for adding lining and side bands on the Malchut or the Beit Yosef, but assume that you can do that. Am I correct in that assumption?
Of course we can. Just keep in mind that it will add 2-4 days to processing time.
 
Can you confirm the dimensions of the size 80 for each of those two tallitot? I'm a big guy, and my weekday tallit is actually a 90, but it appears that the both are only available up to an 80, so I want to be sure about the size.
The Beit Yosef Talit is 170 cm x 200 cm. The Malchut Tallit is 180 cm x 200 cm.
