Sam2: Perhaps you missed what I wrote:
I said that some of them are things that you should actually be doing, as oppsoed to relying on minority opinions or precarious heteirim. Others are things that we apprently should be doing, but we dont simply because of historical precedent, even though we dont clearly understand the heter not to; still others are the opinions of some poskim, while others disagree.
My main point was that those are more halachicly well-founded than the case for Techeiles. If you want to take on chumras, at least take on those which make much more halachic sense. A good way to tell which are which, is to follow the lead of the great Gedolei Yisroel, those with the proper Yiras Shamayim and Torah perspective. This techeiles thing was not taken seriously by the overwhelming majority of our leaders. If you want to take on chumras, start with those that are not really chumras – first get rid of your kulos; then take on the chumras that are more halachicly weighty than this.
Btw, besides skipping a few from the list, how do you address that the Chazon Ish has a strong case for prohibiting using nails in your sukkah; a strong case exists for not opening and closing your refrigerator on shabbos; and some people hold you are not allwoed to wear glasses outdoors on shabbos.
Start taking on those chumras first. Then we can discuss techeiles.
