I am interested in getting 4x4 tefillin in order to have more mehudar parshiyot, but I'm worried about wearing them in a kehila where they wear smaller tefillin. I'm especially concerned about wearing them in the presence of a tzadik or gadol who is wearing smaller tefillin.
Can this actually be seen as yuhara, gaaveh and lack of cavod, or is it something that would not be an issue?
