There's no shortage of treetops almost all the places I fish. Probably 3/4 of the time I just let the boat drift into the treetops. The times I need to anchor I just throw a lasso over a branch and tie off on a cleat. The (very) rare times I fish where there aren't any treetops to drift or tie to, the water's too deep for any kind of pole.
I think non-power poles would be more of a hassle than they'd be worth. At least for me they would.
I think power poles would be nice to have if you have the money. I'll never buy one or a pair, I've no need or desire, even if I had the money, and I don't.
If you know how many firearms you have without stopping to count...
...You don't have enough guns.
If the dollar value of your firearms exceeds the value of your ammunition...
...You don't have enough ammunition.
