A-Zo, thanks for the reply...
If it is possible for you, please speak to your friend who has one of those and ask him if he kicks it and how it is for kicking..! I read a review somewhere online saying kicking htem isn't that great because of the weights around the front (if you look at the two prongs facing towards you..) but on the other hand, I guess it's the closest thing you can get to having a 'real' bag. A problem with the support struts as well is you can't circle the bag
In short, I'm getting the set up as a present, but from someone who knows nothing about bags so it's up to me 100% to find what I want and am happy with..
The bob style bags seem to be more fitness orientated from what I have read and the advice I've got, but useless in terms of actually training / beating on them, but then anybody who has a stand up bag says they can knock it over and that's that lol... Hence the total confusion! lol, at any one time I've decided that all 3 things could have been potentially the top choice.. Thanks again.
