A good punching bag

[KurtCobain2902]

I was just wondering what would be the best punching bag to get, to develop both speed and power in punching and kicking. Im thinking a 100 pound bag, because anything lower might not hold up to kicks.

I was thinking this: http://www.sportsauthority.com/product/index.jsp?productId=9090&cp=&origkw=punching+bag&kw=punching+bag&parentPage=search

Or this: http://www.sportsauthority.com/product/index.jsp?productId=1432816&cp=&origkw=punching+bag&kw=punching+bag&parentPage=search

Sports Authority is right down the road, so hopefully the price will be the same there is it is on their website.

Any advcice on which to get? Or suggestions of other bags all together?

I'd go for the second one, I hate the feel of canvas bags.
The weight depends on what kind of kicks you'll be throwing. Whether it'll be mostly with the instep or the shin. If it's the instep then the heavy bags aren't always a great option because the instep can be quite delicate at time.
Also heavy bags are used by Thai boxers to condition their shins and deaden the nerves so it might be quite painful against instep kicks, but I can't say for certain.
I can't really reccomend things any further than that though, I just hit whatever bag I'm told to :)

Ok thank you.

I'm mostly going to be doing sidekicks, wheel kicks, and maybe occasionally spinning heel kicks. Oh and also, front kicks with the balls of my toes.

Can I leave my Convers Chuck Taylors on when I kick, or is it bad for the bag, even with the anti-rip fibers?

Is a 50 pound bag heavy enough for power training? ANd will it hold up to kicks if I dont have on my shoes?
