... of course, you could use my logic...
... in a standard 54 par round...
... at maximum, 18 shots will require a driver...
... at minimum, 36 shots will be putt / approach...
...Very few courses are without 250-300' holes. Likewise, very few courses are all 350+ holes...
Therefore... your rig should lean heavy towards your putt / approach game... not drives.
That is sound logic. Personally, I'm more comfortable manipulating release angle with putters and mids, while drivers I try to release all roughly the same and let the disc do the work. So my bag is driver and fairway heavy in order to cover all my lines, while the mids and putters each get thrown more regularly.
3 putters / 4 mids / 6 fairways / 3 control drivers / 3 distance drivers
