My first unit was a stock unit and i cutted all myself (Lace and hair) That has worked perfect and fit totaly to my headshape.
So my own hair is growing a bit faster than i thougt, so i have to buy my next piece in the next weeks.

What are the differences between a full sfs stock unit and a full sfs custom unit, beside i could consider flaps and a other density than the custom unit.

I have no problem with cuting all by my self, so i dont know if i should by a custom or a stock. I would prefer a stock if there is no other advantage by a custom piece, because it only took 4 days to get it and not some weeks.
