Need help choosing equipment

[FM3O]

So because of my current work schedule it's going to be hard to get into the gym to train everyday. I decided to setup a heavy bag and a double end bag a long with a few other things in my garage so i can train even on the days i can't make it to the gym. Problem is, I am not sure which heavybag I should go with. Im 6'3 and weigh 160 so I definately want to get one thats fairly heavy. When I was browsing I came across a couple of different style heavy bags, and am not sure which would be best for all around training.

I like the design of the bottom one, because it looks like it would be better for working on uppercuts and throwing punches from different angles. I think they both might possibly be too light. Does anyone have any experience with either of these heavy bags? would a standard 100 lb bag be better?

Also, what are everyone's thoughts on these two kinds of double end bags?
