Just curious I haven't heard anyone commenting on how much better the head positions are in some of the planes. 
The one's I've seen a difference in are;
- Typhoon
 - Corsairs, -1A thru -4
 - Late 109's, G-14, K-4 (haven't checked early ones)
 - Fw 190's
 
It's cool that the head position limit now follows the canopy profile, versus the old straight lines. Thank you HTC.
