I got these strings for my first bow in an attempt to make it a little more legit while I save up for a top-of-the-line Mathews.
I ran the Orange and Black Premium strings on my Diamond SB-1 and I actually was able to twist them a couple of times and get over 70# out of it! They haven't stretched too much, stay true even in the summer and winter weather, and I really have no complaints.
