You better not take my advice,,, or if you do you need to do a lot more talking to your wife, and probably should start now.
I Started out much the same, tossed between the 355 and 380,,,, when they introduced the Lynx a 380 in A-P Snow Camo, a pattern I love for late season,, I bought it!!
#2 after shooting it for a month and trust me it will shoot with any Exomax I know, that was my first Excalibur, they introduced a Mad Max,,, yes I loved it and had to have another 380!! I mean you need something for early season,,,
#3 then the 1000's of reviews on the Micro after 6 months and holding several, I new I had the finest hunting bows Excalibur mad with 2-380's but,,, yep I had to add one. So I had to find out what the fuss was about,,,, yep I have one, after shooting it and seeing just how accurate it could be,, it will shoot 1" @ 60 yards with fixed blade broadheads!! I decided to make it personal, it is now dressed in 100% 3D Deception Camo pattern. I shoot this bow better offhand than any crossbow I ever owned!!
Saying all this I am now in another dilemma,,, I have seen and shot the 355 and "I WANT ONE"!! I am considering another Custom Camo'd pattern for it,, gotta find a way to justify it....
So now my personal recommendation,,,,,
buy all three, you'll need them,,, I Love that little Micro, the Lynx shoots as good as the Mad Max,,, both will take any animal I could ever hunt.
BUT if I could only own one bow,,, God forbid!!! It would be the 380 Mad Max,,,,, Like Sew said 1" groups at 70 yards is as far as I have tested mine, with a scope set on 2.5 to 2.8X with fixed blade broadheads, with 125# KE,,,, I just can't part with a setup like that,, but you need to make her understand,,, you need backups!!
