I tried my coring system for the first time tonight. I had some expert help from my friend whos done it before so that was a big help. I managed to make it through without making any funnels or liberating the bowl from the chuck. I am also pleased with the perfomance of the DVR XP. I did manage to stall it a few times but I was fairly aggressive. Unfortunately I had to shorted the blank about 1.5" because of a crack which makes the last core almost a plate.
Anyway here's a pic of what I started with and what I ended with.
