Having shot the LV1 from Bitberg onwards, it was just amazing to dump paint our of!
The LV1 doesn't look significant, but like diaboro919, it's down to personal preference what you want to shoot.
As mentioned earlier, I used the LV1 through Friday and Saturday of Bitberg before moving back to the Geo3, the differences I found between the two;
1) The LV1 has a wonderfully ergonomic in my hands, the grips are thick enough and rough enough for me to grasp it through dirt.
2) The LV1 is a heavier gun, although some people want the lightest everything on a gun, having weight increases accuracy by stopping any 'recoil' and keeps the gun spot on target
3) The LV1 is quieter then the Geo3 - as confirmed by Stoney on the PE Forum section
4) The LV1 is much much easier to clean down at the end of the day, it is afterall based on the ego design
5) The LV1 is efficient as hell, I shot a hopper, 6 pots and still had 1.5k left in my tank from a 4.5k fill - this is factory settings, lord knows how many more shots you'd be able to get if you knew how to tune it!
6) I have only sold my LV1 as I am leaving the country for a year or so, and as I wont be playing paintball - I'm not going to require a gun. I am actually really sad to see mine gone, but I'll probably get one again if I come back.
