Well. I got my two level 10's today.
First installation into my emag Installation took about 40 min to get it right (including shim tweaking). It may take more to get it perfect.
I tried the a couple of different carriers ending up with a number two. The carrier initially felt tight, but the next larger one leaked air. The number 2 carrier performs well though so it must be the proper fit.
Next came the shims. I held the bolt while pulling the trigger to see what effect each of the shims had. I found that 5 shims caused constant leakage out the barrel, 4 worked but leaked if the bolt was bumped or if the trigger was slightly pressed. 3 shims provided crisp control without premature leakage . There really wasn't much difference in feel between 2 shims and 3 shims except that the air would vent quicker in the event of a blockage if the 3 shims were used instead of 2.
I've stayed with the short stock spring. I haven't got a chrono so I can't play with the settings properly until the weekend.
Update: Well, I couldn't wait so I purchased a chrono. I played with the settings and ended up using the middle(cut) spring. I am able to shoot about 285 consistently without missing a shot due to a tight ball. The largest spring wouldn't shoot when the velocity was consistently below 300. With the middle spring the impact on the ball is very light and gentle. I believe I have found Nirvana in my emag.
Update: I had the emag in a tounament today June 13/2002. When setting it up to chrono using the standard RT chrono method, it would cough with a ball in the chamber. When I fired normally, it seemed to work fine. I though I might be close to the edge of performance so I cut about 1/4 inch of spring steel off the middle spring (not 1/4 inch of length) that I was using. I was able to chrono properly after that with no coughing. After breaking it in it seems to work better and I may have to order another proper middle spring.
I shot about 1200 rounds in 5 games playing 3 on 3. I busted a ball in the breech at the start of the second game. It didn't look like a chop but it made a mess. Other than that it rocked and it felt good. Lots of mag users were at the tourny and I was spreading the news.
I noticed a slight metal on metal sound when manually pushing the bolt in and out of the power tube. It had a rougher feel than normal. Maybe its just something due to tighter tolerences and will smooth itself during break-in. Anyone else notice this? It doesn't seem to affect the operation. I just don't like the feel of metal on metal. Update. The metal contact was between the new power tube tip and the inside of the new bolt. Contact was being made at the front outside edge of the round section of the power tube tip, and only on one side. It'll probably smooth itself out. I'll be keeping an eye on it for wear.
I tried shooting with a squeegy held down the front of the emag against the bolt. That way I could get a feel for the pressure applied to the ball. The pressure is very gentile until about the 3/4 past the feed neck. You can feel the difference by varying the end of the squeegy when you fire. Its quite amazing.
I can see that my chopping problem will be eliminated or at least reduced even if a generic setup is used. I'll be fine tuning mine through a range of settings. Whats the use of a beta tester if I don't put it through its paces. See above comments now that I've updated.
I've installed the second level 10 bolt kit into an old 1993 vintage level 7 automag using the stock spring. Set-up time was about 30 min. I figured it would be much quicker the second time but it takes time to time test spacer settings.
Again, I settled on the number 2 carrier. The next larger one was too finicky. It would work but had random leakage problems.
I installed the shims and again settled on 3 shims that provided the best control close to the venting point without leakage during partial trigger pulls.
Complete details will follow once I have access to a chrono. Done, see above in Emag section.
Not one chopped ball yet in 500 rounds fired without a battery in my revy, although I have yet to use bad paint.
One thing I have noticed is that you have to be a little more careful when you set your gun down. If you lean it on the barrel, it may leak a little air out the front.
Level 10 rocks.

Except for the Automag in front, its usually the man behind the equipment that counts.
