I am seeking a light weight 3-way head alternative to my (HEAVY) 3047.

I noticed this 329:

It looks like an almost perfect compromise, but the bubble levels seem useless to me. With the 3047, I can level the bubbles on either axis, after the camera is on the head. I don't think I can do this with the 329.

Does this seem like a drawback? Anyone else have any other alternatives I should check out? I tried thie 3437 head:

The weight savings is great, but, the knobs seem difficult to tighten firmly, and, of course, I really miss the bubble level style of the 3047.

Thanks for any comments.
