Just strung mine up. I also found that the string is short. I had to bridge my mains to finish the last string on both sides. I just cut my string in half as I usually do, so if you do the same, keep in mind that you may run short.
Also, it did string tighter than normal so in my opinion, the "pre-stretched" Kirschbaum did have a noticeable difference in tension. I would drop it 3-4 lbs to compensate.
Full review to come after playing more.
