There is an omission onOne solution has been omitted for this answerquestion - most people who stack actually tend to use Zerene Stacker - it's the only package that has various user generated plugins for substack slabbing. If you look through Flickr there are twice as many Zerene pics as there are for Helicon. Helicon is faster though and suits lab workers better, ZS better for photographers. Both this and Helicon are the class leaders.
