I play a 6 string bass, and ive only been playing for 8 months. Dont get me wrong for only playing 8 months i am truly blessed, but the only reason and i mean only i play a 6 string is because I was in GC playing around with different basses and i happen to pick up a six, and ever since then i couldnt drop it. The feel of the neck felt so natural to my fingers, and my hands. It felt so, so comfortable, and still today i play my 6 just because of its feel...i hardly ever play the C string. I have a 4 and a 6, i skipped over the 5 just because i loved the feel of that 6. So in saying that....there are different reasons people play different basses, so all in all....just do you.
