block is only really good for field points it will hold up very long... The block 4 x4 i can't speak on. but if you want to shoot both field point and broadheads try stanleys hip shot otherwise get 2 targets one for field points and 1 for broadheads morrell is good for this they make yellow jackets for both bag for points and block style for broadheads both around 30- 40 dollars a piece... you start shooting your broadheads into the block you will find it won't last long unless it is the new 4 x 4.......
