Hi Tom, I recently purchased a Manfrotto monopod along with a ball-type head and I must say I am very pleased with it as it is quite light to carry, although some of their models are much heavier. I wouldn't want to use it as a walking stick, but I wanted to mention that some outdoor shops carry a line of very sturdy but light fully-adjustable walking sticks. My office mate bought me one of those when I retired in 2006 and it has been most useful because the walnut knob head unscrews to reveal a screw made for camera mounts.

I've used it many times to steady up a shot while walking. My premise is that I think it might be better to rely on a good walking stick which can see some use as a monopod, rather than use a monopod as a walking stick and risk having it give way. At my age, I don't want to risk a fall on these old hips.

Loved your photos!
