RE: Bag targets.....All the same?
I use the 'Rag Bag' from Third Hand Archery. I love it. Simply fill it with old cloths and forget about it. It is light enough to shoot outside during the summer, and move it in the basement for some winter shooting. I haven't sent thousands (and thousands) of arrows at it without a passthrough. And you can't beat the price.
If the thing ever wears out, I wouldn't hesitate to get another one. JMO of course.
