I really love my 24-70 L, its versatile, fast, great IQ. However, I have recently been looking for something a little lighter and with a little more range to use for a walk-around lens, so I bought a 24-105 L, and I really like this lens too! It's perfect for when I go hiking; its lightweight, sharp, IS is handy when I need more DOF, it doesn't have the huge hood like the 24-70 has, it really fits the 5D well.
My intentions were to keep both lenses, as I think they serve different purposes. The 24-70 is great for indoor work, or in situations were you want a very pleasing out of focus area (24-105 out of focus area is definitely not as nice as the 24-70). The 24-105 is great as an outdoor walk-around lens offering lightweight, longer range and IS.
Now I'm beginning to rethink my strategy a bit. I'm considering selling my 24-70 and picking up a 28 f/1.8 and a 50 f/1.4 (and maybe a 85 f/1.8 ) for some real low-light capability. I've never had much in the way of primes--I've bought and sold two 50 f/1.8's because I just don't use them much, but there are times when I'm at parties or out with friends at bars or restaurant where I don't want to use a flash but even the 24-70 isn't giving me a decent shutter speed. I also think a couple primes would be a little less conspicuous which would be nice at certain times. But I feel like if I sell my 24-70 to buy primes that sit in my bag because I really am more of a zoom guy, I'll be kicking myself in pretty short order.
So I don't know what to do. Any thoughts?

however as to what to do I guess it really comes down to your needs
