He used threaded bh on mine...I feel they give a better seal although I have no evidence to support this. Threaded does give you the ability to remove the pvc fitting from the bh. As far as flow reduction going from 1 1/2 to 1" or 3/4".....maybe an engineer can chime in with the surface area of one 1 1/2" circle compared to four 1" circles or five 3/4" circles. I'm not an engineer but if the area of you outputs added together are equal to or greater than that of your feed line...aren't you OK as far restriction concerns? This hobby makes me regrett all that snoozing I did in physics class!
