Bought the 2 + 2 set as the tuning peg on my D string was slightly bent and wouldn't tighten, kept skipping cogs. The D peg is the highest on the head stock so first one to take the brunt if the bass falls over. This was a near perfect replacement, swap out was easy and the screw holes aligned 95% which was good enough. The elephant ear is almost the same size as the originals (fraction larger) so doesn't look out of place. I now have 3 spares. Would have liked 3 + 1 but 2 + 2 was best available.
