Thanks, Slasher, Neil and CJ.
CJ, I'll try getting closer to the cue ball. I'm 6'3" with long arms, so I'll probably need to bend my bridge elbow (more). I currently put my right foot on the line, and stand a cue's length from the front of my right hip to CB. I see what you're saying about it being easier to turn on the power if I'm not so far away, and sometimes it does feel like I'm reaching for the ball.
