good post whitey. anyway, yeah, totally agree its bad for your hands, not just because of everything whitey said, though its all true... but because the actual force on your knuckles, because they are bones, is bad. you can damage the tiny parts of the bone and over time push them back into your fist. and yea, probably any type of heavy bag would require gloves for the above reasons. personally, i like the fingerless gloves because they feel more like a fist than any other glove, though any bag glove (with enough padding for my rock hard denim filled 75lb-er) is acceptable.
