I love my Mini as well as the other lines of EVOLS'. It's a very well-built platform. Like others have stated though if you like to tinker and constantly change reg and HST settings, there are more steps to it. If you do end up getting one and plan to make adjustments to the reg, I suggest picking up the AAA Barrel Removal Tool from AoA. The cost is $98.00 for the tool but even the tool is very well made.
The only other gripe that I haven't mentioned to Tom, AoA, or anyone else is that some of the magazines I received didn't index. I had to open up the magazines and reset the coil springs so they would advance to the next pellet and it hasn't been a problem since then. It's simple to do though once you've figured it out lol. I'd also suggest getting a set of SAE-sized ball bearings because I did lose one of them while in the process of dissembling/assembling the mag.
The EVOL Magazine schematics have the size listed as 3/32" but when I compared it to the other mags, it looks like 1/8". I would make a request to AoA to test the magazines before shipping them out to you. Tom will respond to you if you PM him here or email him through their website. He has sent me some parts upon request and so far, I'm happy with their customer service. AoA will also take care of you if you're not able to get a hold of him.
In regards to the cocking effort, it depends on what power level you have it set up for like some other platforms. The cocking effort is smooth and there is no grittiness. Just a little more effort at the end of the cocking cycle. Like Douger mentioned, you should get about 40 shots at about 28 FPE/840 FPS with JSB 18.13gr on a 270 BAR/3900 PSI fill with reg set at 131 BAR/1900 PSI or 134 BAR/1950 PSI.
I also have the L2 but I'm not sure about replacing it with the EVOL Mini because I personally believe they are different platforms. I can understand though due to cost or having too many PCPs' to justify. The trigger on the EVOL is sweet though. I recall Claudio Flores (Patagonia Airguns) saying that he was able to adjust it down to around 4 ounces like his Thomas rifle in one of his videos. With all that being said, I don't think you would have any regrets about picking one up.
