I used aluminium wedges "back in the day" as they say. I think today's plastic wedges are superior. No worry of pooching your chain with the plastics.
I think the hardhead ones from Beaver State plastics are pretty good, as are the k&h red heads. The hardheads have a textured finished that helps them bite, but not as well as some with teeth. I have some with "teeth" that work gooder in the winter, but I don't do a lot of winter felling anymore. Forget the brand off hand maybe oregon.
If I need a lot of lift for wedging a tree over, I like Black Bear rifled wedges for stacking. They have a v groove that locks them together and keeps them from slipping sideways on ya.
