OK, this is probably a silly question but I'm looking for a lightweight ballhead which will support at least 7 lbs for a new travel setup. Yeah I've read all the bs reviews, etc. but I'm looking for real-life experiences here. As I, ahem (cough, cough), get a bit older I find that weight is really becoming a problem on longer hikes. That I have a herniated disc only exacerbates the problem. So, how about a little love for an older fart?
