You certainly can't go wrong with the .25 LA as I said, that's what I have. The APC 10x3 and 10x4 are what I'm using too. The LAs are light engines, the .46 LA is only 12.5oz with muffler and is a viable option in my opinion for those who want ballistic pull-out.
If you want to play it safe you can't go wrong with the .25LA
What's your response to some of the earlier posts saying the 46 is too much engine for the Mini?
I also think it's strange no one has mentioned the 40 LA. If the 46 may be too much, and the 25 may not be enough for some, maybe the 40?
