Hi HTA Brains Trust
I am making a three buttoned hacking jacket. I have baste it up but not yet put the sleeves on but obviously, when i have the shoulder seams sewn, tried it on with the shoulder pads placed in (who doesnt?) I seem to have a long front balance as the coat is "A" Shape down the front edge. I know i should complete the baste with shoulder pads, sleeves and collar but obviously it would be good to give the first fitting its best shot if i can sort out a bit of this "A" Shape. I have done quite a bit of reading in books and various HTA Forum pieces.
I have found this in the "Tailoring Suits the Professional Way" by Clarence Poulin

I have pinned out the shoulder like Fig 36 and 3/4" brings the front edges in line
The solution is this

Poulin has taken off the 3/4" right across the the shoulder AB to CD which effectively moves the neck point A over to C. I had thought we should try to keep the neck point in line with the original pattern and the dart. I thought the neck point line was King? So I amended my pattern like below moving the pattern straight down the neck point by 3/4"

Once i did that I then I found that Rory had made this useful post here https://www.handcrafttailor.com/forum/general-discussions/clarification-on-how-to-make-balance-adjustments

Even though it is for increasing the front balance i can reverse it for reducing the balance. This would be taking out a wedge in the Chest for a reduction in the front balance and adding a wedge to the Half Back. This also moves the neck point over (so obviously not king!)
So after all that, my question is this: What's the difference between the three options?
Poulin's moving parallel to the shoulder seam thus keeping the shoulder angle and moving the neck point
Mine with moving down the neck seam thus keeping the shoulder angle and neck point in line
Rory's cutting the wedge out and thus moving the neck point and changing the shoulder angle
Supplementary question in relation to the relative location of the breast pocket which I have already put in:
a. Poulin's and mine will move the effective location of the breast pocket up 3/4"
b. Rory's will also move up but not as much - say 5/8" but will change the pocket angle
Does all this matter??!
Cheers

Thanks John. I had read the later section in Poulin's book about sliding the back up. But I got the feeling that this was a "secondary" method. Poulin says "But as this method necessitates scooping the armhole and cutting from the top of the revers, most tailors prefer to use another means of attaining the same ends" then goes on to describe the back method. It made me think that the front option was a better option overall and the back option a bit lazy and thus not as good. What's your thoughts on that?
