Hi shawn,
Very nice! I have got two HW 90s in .20 and I love them, though they almost drove me mad at first with tuning and maintenance/repair issues.
At what power is your rifle set and what calibre? Mine are at about 13.5 and 16+ ft. pds. I have found that they are just as hold sensitive as spring powered rifles, and the position of my forehand is critical to balance.
