In @jcarcopo 's case, I believe it will be more about finding the correct balance (vs 'upgrading'). Break in was significant, and lengthy, with my SEs. If that holds to some degree with the Encores, as you say, time will tell.
My point is general in nature. My system is 100% different than when I had the Double Impacts. I believe Tom's ( @mac48025 ) system is as well (or close it). I see a similar pattern with other SE owners (not 100% correlation, of course, but quite high).
Mentioning this for those considering moving up from the Double Impacts or those making their first DI vs. SE / Encore / Ulfberth purchase.
In other words, if you are tempted, know what's likely ahead on that beautiful, wonderful path.
