From https://judaism.stackexchange.com/questions/12979/list-of-techelet-wearers/13027#13027: Hacham Gabriel “heard from a talmid .”
His tallis in Yeshiva is regular.
From Yehoshua Yankelewitz:
“אני שמעתי את זה ממנו, וכן מאחדים מתלמידיו.
כמו כן ראיתי את אחד מתלמידיו (שנמען כאן) קושר לו את ציציותיו עם תכלת.
והוא הורה כן בפירוש לתלמידים אחדים גם כן.”
“I heard it from him himself, and also from some of his talmidim.
Also, I personally saw one of his talmidim (who is addressed here) tie his tzitzis for him with techeiles.
And he also told a number of talmidim explicitly to do so as well.”
