That video now makes me question whether I should get the barrel grip model when i get myself the Carvex. Had initially decided against it as I didn't really like the feel when I (very quickly) tried it out at LV. Maybe I should play with the demo a bit more. Seems to be some advantages with the barrel grip model when it comes to precision.
Certainly something you want to try at a dealer if you can. I love the barrel and grip now that I switched to it and cannot imagine wanting to go back to a D-Handle. Personal preference for sure and one might feel better to you than the other.
