I own this year's Freak 30 (around 250 hits on it) and had the opportunity to swing a brand new DC41 last night. Performance is very good on both. Of course the Freak 30 was better with more hits on it. I was very surprised with this year's DC41. Out of the wrapper performance to me was comparable to last year's and the white DC41 with about 100 hits. It didn't ping as much as last year's and the 2014. I think this year's DC will be comparable to 2014's in performance.
Some differences I noticed with the DC vs 30:
1. Barrel on DC is crisper. I know it's new, but I remember the feel of the 30 when it was new too.
2. More feedback on the 30. You'll know when you get one with the 30, vs. being surprised how far one goes on one hit by the DC.
3. Stiffer handle on the DC. The more you hit a 30, the more the handle will soften. I only felt the DC flex once (when I hit one off the end).
We only hit 52's btw.
