I think its time to retire my 100lb century heavy bag (might mount it as an uppercut bag). Can anyone suggest me anything? I did a bit of research and came across these 2 articles http://mmapage.com/bestheavybag/ http://www.mightyfighter.com/top-10-best-heavy-punching-bags/ Both recommend the outslayer heavy bag. What do you guys think? Anyone got any other suggestions? Thanks!
