[Avodah] talis qoton

[Mandel, Seth]

It had NOTHING to do with t'kheles.  The reasons, as RYBS mentioned them, have to do with the minimum size of a talis, where is must be worn, and how it must be worn.
As I am sure has been discussed at length here, R. Chaim felt that one is yotze l'chatt'hilla without t'kheles, and, addrabbo, would not allow the wearing of t'kheles, not the Radzyner's nor that of the Ptil Tekhelet.  RYBS discussed this shitto (in the name of the Beis haLevi) very eloquently in a yohrtzeit drosho.

Daniel Israel:
<Which would seem to me to imply that if you are choshesh for the Mordechai's position you shouldn't wear a talis katan outside on  
Shabbos where there is no eruv.  I've never heard anyone suggest that chumra, although I was once advised to be machmir in the minimum shiur  
to avoid the issue of hotza'ah.>
It is well-known (or should be) that R. Chaim Brisker did not wear a talis qoton outside on Shabbos, because he was choshesh that one is not yotze any mitzvah with one, for a variety of reasons.  He also did not make a brokho on wearing one, but following the Gra and others that the brokho should be made on the talis godol.
