Looking at weibad fortune cookie or tater tot canvas bag. Will be a used as all around bag for range, hunting and what ever else. I shoot bench with bipod, prone with bipod, hunting blind ground blind etc etc. Whats the size difference between the fortune cookie and tater tot. Does one outweigh the other due to size. If anyone has used both as rear support which one do you prefer. Which ever way I go it will be heavy fill.
