Q: "I have a Chassidishe friend who I told about Techeiles. He told me that due to financial expense, he would choose Radzyner Techeiles over the murex, for the following reasons: 1. Breslovers, Radzyners and other Chassidim wear the Radzyner Techeiles based on the writings in Nitzutzei Shimshon, 2. He's seen other Rebbes wear Radzyner Techeiles in their Tallis Kottons, and 3. He felt that both are good as long as the issue with "Kala Ilan" is dishonesty in selling/wearing on and saying it's the other, which is one thing Radzyner Techeiles isn't accused of. My question to you is, do you consider it to be a sin if someone chooses to wear Radzyner Techeiles over murex, especially in light of the above? As both a Posek and Chassid?"
