I was just going to ask a similar question. I bought my first bow last spring. It's a 'Prowler SE', (2004 model I bought brand new as a holdover) and I don't know what kind of strings it has. If Martin's DH strings are new for '06, than obviously it's not the one on my bow. Mine is showing some fraying and peep movement, and will be replaced very soon, so I was wondering what string I have now, because I don't want another one! Right now I'm considering Vapor Trail and Wolfden strings, but being a relatively new bowhunter, I am always open to suggestions!
