great string
 

i purchased a 8190 string for my katera from proline after a lot of research and it paid off. string came in mail in 5 days and was precise measurement well made and tight served. installed harness and absolutly no stretch or peep twist after 200 shots. my cams are marked on both ends and still perfect . i never had any string to do this. ill let u know how it holds up. great product proline.
