those 2 springs naren, will go just as tight as 5 normal springs. theyre significanlty shorter (by like 30%) and can be stretched to a total lenght LONGER than a normal trem spring gets stretched. You have nothing to worry about. the 2 in my S7320 got it to take 11-72s in B and i was only about 2/3 to 3/4 of the way through the travel
