I thought EZ was going for the wound G because he bought a hollowbody.
For whatever physical reasons a wound G might be justified, in my opinion, the wound G makes for a completely different style of playing - lead anyway. I mean, I can wiggle around a D string and bend it to pitch, but not with the control or precision that I can with a plain string.
Tone-wise, a wound G offers balance and back when these guitars were designed they worked around 4 wound strings. However, in terms of pitch and melody, the plain G has advantages.
You can say I am a puss, but when I tried 11s or even 12s back in my SRV days, I thought the tone was too thick. 10s are a goot compromise of maliability and bright/crisp twang.
Try the wound G, but don't feel bad if you come to the conclusion that the plain G better suits what you want to do. Hell, try the flatwounds, too. I always thought they had a really unique cool sound and they last fricking forever. They are dead when you take them out of the pack.
