Haha I know what you mean, it does seem pretty random - I can appreciate a bass that just does one thing but I also enjoy having massive possibilities - the two basses will compliment each other that way. As I know the bass is capable of more with a simple mod, even if I don't use those extra things, it seems silly not to have them.
Most of all I'm just delighted with the core sounds I'm using now, and this is after only a couple of days - I think in time I'll get to know it even better, and of course have yet to try it in the all important band setting which can be make or break!
