hook? like when you are drawing and the end of the line becomes a hook? If so it's just a flaw in sai with certain tools. I believe if you switch to the air brush, you won't have that happen even at high stablizationg settings.
yes actually i have Sai2. I notice that one doesnt have the issue! Its because i wanted to use Sai V1 and i noticed that the hook problem would happen,and i stayed with Sai2 cause Sai 2 didnt have the issue.;v;
