Jedediah hello and welcome, man where to start.....well I have owned a .22 cal and a .25 call in the kalibre cricket. You are going to get a bit more shot count out of the .22 and it will be quieter for you. However, the trade off is power. A not so good shot with the .22 will result in a un humane kill, but with the .25 well it normally does the job on small game. IF, your shot placement is a little off. Accuracy is going to be great with either of them, out shoots me all the time! Now, I didn't buy the Colibri mainly because it didn't come in .25 cal. But from what I read and have seen, it is definately quite, and for small game, it has mooorrreee than enough to take any of them. And your going to get plenty shots. The cocking mech. Is much better than that of it's bigger brother. IMO. It still comes down to personal preference though. I sorta look at it like this. If I buy it and don't like it then just sell it and buy another. Or if you have the funds just buy both then get rid of the one YOU don't like as much. lol.....I know decisions, decisions. That's what makes this stuff so much fun! Well I hope this helps ya out. Best, with what ever you get. Steve
