Thin Arrows vs. Thick Arrows, Where is It?

[CPF0RY0U]

One thing I don''t like about this forum is that you cannot sort by date after you see the search results....

I''m looking for the thread with various pictures and opinion on thin arrows vs. thick arrows, and the different shape hearts and how it affects the way pattern scintillation when it comes to H&A diamonds.

If you really want to get hard core on what the limits of the lgf% are when it comes to leakage read this article:

On the other side of the coin the effect of shallow pavilion obstruction can be reduced by narrow arrows also.

Some angle combos are more sensitive to lgf% than others.
