I am a skinny guy. I never worried about wieght I spend so much time looking at my fingers on the board I don't have time to notice wieght.
There is benefits to being a hack.
It is the missing string that keeps me from wanting it really bad.
My Stingray 5 is the heaviest bass I have ever owned and probably my favorite of all of my EB's. There is just no substitute for the low end growl that it has. I am one of those who does the 4 hour shows.
I find it does not hurt until the next morning but I would not consider getting rid of that bass for a lighter one.
