Cold weather use isn't a big deal for me. Not that it doesn't get cold here in Cleveburg, but I'm not outside fussing with the air hose when it is.
I do want something that uncoils easily, lays flat and doesn't coil around your feet all the time, and coils back up easily. And with a long hose, lightweight would be a plus too.
Reviews on amazon are the usual mixed bag...best ever...worst ever...
I won't be giving it full time heavy use, so extreme durability really isn't a requirement either.
I think 1/4 inch is fine, won't be driving sanders or sprayers or impact wrenches, just typical nailers and staplers.
Don't mind spending a bit to get something that won't annoy me for the rest of my life.
