How confident are you in your u4/3 kit?

...on the situation.  I am not confident in the kit in certain situations, especially low light, high ISO because the only fast lens I have is the 20 mm f1.7 and the GH1 is not that great in low light.  The GX1 I am more comfortable with in these situations, but still limited by only one fast lens.

In bright light travel situations, I am very confident in the 14-140 as the jack of all trades, the 20 for low light night shots, and 9-18 for ultrawide.  It is a very lightweight travel kit, even with two bodies.  I can carry the GX1, 14-140, 9-18 and the 20 in a single lightweight bag everywhere I go.  If I don't want the tele, I can go with the 14-45, and it is even lighter.  I hardly use my 45-200 anymore, but when you need the tele, it is better than 14-140.
