VERY timely thread!
Due to wacky circumstances, I have two identical golf bags with two identical putters and two identical drivers.**
So
In my previously unused bag I put a driver, 4H,6H,8I,W,LW and putter.
Plus a handful of tees, golf visor, gloves and 6 balls.
Now I carry that bag everytime I walk 9 holes after work.
If I'm in a weekend tournament where carts are required I use the other bag with all my other clubs* and balls and towels and rangefinder and retriever etc.
My scores have actually improved!
* I still have driver, 3W, 5W, 3H, 5H, 7I, 9I, UW, SW, putter and lob wedge.
** Bag was stolen with about $35 in a pocket. I replaced most of my clubs. Bag showed up behind the shop at the clubhouse a month later with money missing but everything else intact.
