Just a newb view, but I have seen some vids on the vector where the mag release button can be inadvertently operated when gripping the front of the rifle. Not that I'm in the market for one, but it's something to check depending on your grip style.
From a victim's point of view I can attest to the accuracy of the evo. Seems to have heat seeking bbs and with a torch they seem very capable ?
Again, just from lurking on here, don't a lot of users disable the recoil system on their rifles? This might be a consideration if you're paying for a feature you won't use. Although I understand that TM don't make any bad gear
Let us know what you decide and how you feel after you've played with them all. I'd be interested to know how your evo works at longer outdoor ranges. Does it have the range of the longer crb style m4 variants? I was initially put off the evo as it didn't seem to be easily upgraded with external bits, but having seen them up close, they have rails top and bottom, so can probably accommodate all the usual add-ons. What's your setup like?
