Um, yea... i think ill just reitterate what has already been said heaps... but one last time... for the record:
T = p x (f x 2L)^2
T = Tension
p = mass per unit length
L = Fixed length (what scale bass)
f = frequency
Soooo... tuning to a lower note... keeping all other values constant, will make tension go down...
Changing to a higher mass string and tuning to the same note will make tension go up
easy enough
Tension is proportional to: string mass, scale length, frequency
So increasing any of those will make the tension go up, decreasing will make it go down...
Edit: Personally, I have a light set of strings on my 5-stringer ATM... the B string is a 110... its ok if u have a soft touch... but still feels a bit awkward to me, so im gonna chuck a 130 on.. wo0t
