Chabad Tallis: Unique from top to bottom

We get a lot of customers looking for a genuine Chabad tallit, but we also have customers shopping for what I guess you could call a pseudo-Chabad tallit. For instance, today we received the following inquiry:

Is there a difference between your Chabad Style Tallit and your Prima A.A. Tallit with Ari/Chabad tzitzis?

Any advice for me?

Thank you for your time. It is wonderful to be able to purchase from an expert.

The question is a bit involved, so let's first clarify the tallis, and then move on to the tzitzis.

There is only one small difference between the Prima A.A. and the Chabad Style: the Chabad style has a second hole beneath the main tzitzit hole on each corner.

The traditional Chabad tallis has a number of other differences:
1) No atara - This is exclusive to Chabad. They hold that the atara sort of deflects attention from the essence of the mitzvah of wearing a tallis. They don't really have to worry about the issuing of making sure the tallis is worn the same way every day because the lining takes care of that.
2) Lining - Purists insist on silk, which tends to make the tallis slippery. Others choose a cotton lining.
3) Corner squares - Made of silk. Usually they are synthetic, or wool on high-end talleisim.
4) Striping - A Chabad tallis has a lot more black striping than a standard tallis. Some non-Lubavitchers wear a Chabad tallis simply because they like the striping.

Now to move on to tzitzis. Chabad tzitzis tying, which is based on the Arizal, entails linking the windings into groups of three, which is called a chulyah. This takes a bit of expertise. A lot of tallis dealers, both online and real brick-and-mortar stores, don't have the know-how to tie Chabad. In fact, a well-known handwoven tallis maker I work with just outsourced me to tie Chabad tzitzis on a tallis they made for a customer of theirs.

The other element of Chabad tzitzis tying is the halachic innovation of the second hole beneath the primary tzitzis hole. The issue behind this is the problem of keeping the tzitzis on the side of the tallis with the fringes, so that they hang down properly -- without having to scrunch up the fabric, which introduces a new problem of bringing the tzitzis hole too close to the edge of the tallis. Most poskim choose one attribute or the other, but Chabad invented a way to have your cake and eat it too: they don't scrunch up the fabric, but they anchor the tzitzis in place by looping the shamash string once through that second hole. In theory you could do this with a difference tying custom. In fact, we once had a customer who wanted Ptil Tekhelet tzitzit tied according to the Raavad on a Chabad tallis, and using that second hole was important to him for this reason.

I see I'm being long-winded. Apparently I was avoiding this customer's main question: "Do you have any advice for me?" Because the truth is, no I don't.
