I'm supposing it will take you awhile to find what you require from a stick. After a few years at this, I find that less than 1 out of 5 of my early sticks is satisfactory.
One of my crucial tests is how good the handle feels in my hand after an hour or so of walking. Everyone's grip is somewhat different, but looking at the handle, I wonder if it is big enough to allow the hand to shift around over time, and so prevent muscle fatigue.
Aesthetically, the finely polished handle doesn't seem to quite fit in w. the rougher shaft. Not that contrast isn't good, but it seems a bit much in this piece.
I've found a lot of variation within every tree species. For instance, I use both sycamore and sassafras. Both are fairly light woods, but some pieces are stiffer and finer grained than others. Also, the variation within species may mean that a piece of hard maple is heavier than one of oak of a similar size.
I have enough sticks on hand that I can get picky, and set aside pieces that are a little to springy, or too bent to have an even balance.
