I've ditched them both recently matey and replaced with green planet Massive.. it's doin a great job as far as I can see and waaaaay better value. My advice.. and only my advice lol try massive at much less cost first.. if you don't like it.. splash out on the AN stuff and try it.. my buds are much harder and stickier and a good bit frostier than when I used big bud and overdrive. Its replaced big bud.. overdrive.. and bud factor X in my program.. add the cost of a litre of those 3 up and thent.. when you regain consciousness.. check out the price of a litre of massive good luck brother
