I don't see enough difference in the Izzo bag and the TGM bag to warrant spending an extra $100+!
At the minute I use an old medicine ball that is covered in suede! It has no give at all though.
Can I ask whether LB Golf advocates hitting the bag with or without a ball. I watched Chuck Evans' clip on you tube and he advocates hitting ball then bag.
