An old set of steel Buckingham climbers with T pads and pole spurs that I use on poles and sometimes on thin-barked trees.
Climb Right aluminum climbers with Super Climber pads and 2-5/8" tree spurs, removable, with a set of the 1-5/8" pole spurs.
I haven't had a chance to try the pole spurs on the Climb Right climbers, yet, but probably will next spring. This set came with the Climb Right aluminum pads that I absolutely hated. I, too, have chicken legs... the aluminum shin cup part would immediately dig into the front of my shins as soon as I started up the tree. Tried all kinds of additional padding and adjustments to the climbers, etc. but just couldn't make them work for me, even with 16" linesman boots. Spyder Mfg. replaced them for me, at no cost (they even paid the shipping to return the original ones). They sent me the Super Climber Pads that use two straps (they sent those, too) and that don't have steel reinforcement in them. These are real comfortable and nothing digs into my legs, anywhere. I've climbed on them with the linesman boots, but not with my lightweight climbing boots, so I'll try that arrangement as soon as I can. I don't mind climbing with the tall boots, though, because I like the extra leg protection... they can be pretty hot in the summer, though, and take a while to get on and off.
I don't notice the weight difference between the steel and aluminum ones, to be honest, but with the linesman boots... well, there's a little extra weight involved with just those, so perhaps I'll notice it more when I try both out with the lighter boots. The Super Climber pads are hideous, big and ugly bastards, but they're comfy.
