MY recommended pattern:
(12) 11 4 3 2 1
10 9 8 7 6 5
My reason is that this arrangement reduces the crossover or touching of wound strings, which can affect tuning: if the string you are tuning crosses
or touches another string, it can change the pitch of the other string being touched.
I don't consider break angle, convenience or "balanced forces" to be as important as the clean and unobstructed arrangement of strings in the pegbox.
Where the hole in the peg is is of no consequence as long as it is not up against the wall at the small end of the peg, which would interfere with the
peg seating properly to hold the tension. The break angle can be relieved by using a top nut as wide as possible (at least 4mm) with a full radius
into the peg box, round groove guides larger than the strings, and a break in the edge to the fingerboard.
Wound strings should be used full length with all of the string wound on the peg with at least one overlap, and the final position directly in line
with the string's guide in the top nut. The nylon strings need to have a half hitch knot through the peg hole to prevent slipping, wound strings only
need to be inserted in the hole and overlapped at least once. Loose ends in the peg box can get caught on other pegs and interfere with tuning
smoothly.
Finally wind the strings neatly to avoid any overlap at the output. The overlap can cause a lump in the peg diameter, making tuning more difficult.
The 12th peg can be used for a tuning using a high F at the first position, with the 1srt and 2nd strings shifted down, never for double bass strings.
