I did a search and while there is some info out there it's very sporadic and fairly old. I may have the opportunity to endorse this company and I was wondering what any current users have to say about them, specifically any of their roundwound sets. One of my favorite players Robert DeLeo from STP has used the Power Wound nickels for years. I know that in and of itself is no reason to think these are great strings but I was curious as to other's experiences with SIT. They seem to be a very small company based out of Akron, Ohio and I don't see the usual big names that you see with other brands on their endorsement page but who knows, maybe they are quite good.
