“The Techeilis is no different.”
Seriously? A mitzvas that hundreds of thousands of yidden would be able to perform daily the way the torah prescribes it is something the gadol hador has no time for? Nobody thinks it is important to ask? Rav chaim himself doesnt think it is important to research? Does he wear tzitzis? Did Rav sheinberg z’l, who was rather meticulous about tzitzis spend any time on it? Why not?
