7-8-11-13 with Alternating Chulyos

Received from someone who wishes to remain anonymous. To quote:

Regarding pattern:

The idea is to:

(1) capture the nice symbolism R Aryeh Kaplan gives the Ashkenazi 7, 8, 11 and 13, the same groupings as the 39 melakhos; and as halachic argument

So…

You will see that the Ashkenazi implementation of the Sifra’s 5 knots (plus Tzitzis=600 plus 8 strings equals 613) is fully there. Ignoring color, the windings are grouped by the knots in 7, 8, 11, and 13 windings.

Ignoring those knots for the moment, we have 13 Chulios of 3 windings. So far, this is the Baal haTanya’s compromise.

He defines Chulios by a daisy chain of side-knots grouping the windings into three. In addition to the big double knots all Ashkenazim use for the Sifra:
7 = 3 + 3 + 1
8 = 2 + 3 + 3
11 = 3+3+3+2
13=1+3+3+3+3

Except for two broken Chulios – the last of the 7 convincing with the first two of the 8, and the last two of the 11 combining with the first of the 13. And I was uncomfortable with that. Im terms of the daisy chain the 1s and 2s were really in separate knots. I didn’t feel those Chulios were real.

And besides, the majority opinion – including the Chinukh, Tosafos (and for Ashkenazim, we often pasken based on the idea that Tosafos themselves were Rov Rishonim), and the Gra – is that a Chuliah is a group of windings of a single color.

So, if you follow “the majority position,” and look only at the color of the windings, you will see 13 Chulios of three windings.

Regarding String Ratio

The idea is to:

(1) capture the nice symbolism R SR Hirsch (Collected Writings vol III) gave for Rambam strings;
(2) minimize risk of messing up what one could be doing with Lavan on the chance that we are wrong in the identification of the banded dye-murex (which taxonomists have re-labeled Hexaplex trunculus).

So…

Rambam strings. Because R Hirsch and to make sure the only string that isn’t white and the color of the Beged is definitely being worn only to fill out the 8. For example, had one goes with the notion that Tosafos and Raavad were right, one would be harming the lavan half of the mitzvah.
