1) does anyone else get the frozen hand stiffness after holding the blower tube for an hour... and it takes about 10 minutes before you can move your pinky? And i wear gloves.. 2) with the blower on your back, how tight do you leave the straps? i have 2 blowers, one they're loose, and the blower sort of hangs off my back, pretty comfortable. and the other is more tight, almost flush against my back. I've been using both machines alot lately, and have wound up with some backaches... is there actually a proper way, or is just comfort and preference. Any older guys talking from experience, who can say..don't make the same mistakes i did, and mess up your back.
