Heiim with wide left regel
As far as I could understand, Mikdash Meat and Otiot Harav consider posul due to shinui tsurah when the left regel of a hei is wide as a moshav, instead of being a iud-like point.
It should also be thinner than the area of blank klaf (haparuts merube). In some hexagonned-signalled above, the paruts could be most of the area, but still the left regel seems to be a moshav. And what should then be the border between a moshav and a point, 1k(one ovi-kulmus)?
