I haven't gotten a 10# (yet), but I like the look of it very much. I am considering getting a 10# for the treadmill more than for extra weight while lifting.
I can see the use of the 10# for lifting if I just can't lift the barbell over my head (due to too much weight) and want to bump my lifting weight a little. A 20# adjustable (IMO) would be primo, though, as one could use 10# if that's what they wanted.
But I don't just want a Cathe-branded item of something I can currently buy at Walmart. I want a nice vest in the vein of the 10# one, if that makes sense.
