Grazed,
You should list the make and manufacturer of the bow you posted. Nevermind I found it on your thread.2004 PSE FIRESTORM
I'd bet that they have not changes that bow since about 1990 or so. With today's bows at the same draw weight and length as that bow you can pick-up higher speed and KE. That's why I'm recommending something new.
