The exact weight depends on the individual instrument, but I think in general its around 9lbs., though I could be mistaken.
I had no trouble holding mine, 9 lbs sounds about right. I'm 6.2', but maybe a smaller person would have some trouble. no problems with weight here.
Well I'm 6'6" and weigh in at 250. I workout every morning so I ain't too concerned but I am fighting spinal stenosis, some nerve damage and a blown disk. I think anything 10lbs. and under is good to go. The Cirrus-6 weighs in at 9.5 and for some reason it feels lighter than my MIM J did. Maybe its all in my head?
