I assume he means smoothflow, which would be interchangeable with the pulleyboys system or the wbodystore system. There isn't as many around as for the ZZP/Intense systems, but they're still sold regularly on the forums.
The reason I said Smoothflow is because they are located about 10 miles form me . So they are local to me
