That was my first bow lots of years back. Rode my bicycle to a yard sale and bought it for 5 bucks. Still have it, but it's on loan to a buddy long term haha.
If I remember right, it has real thin tip overlays. If I were to try a Fast flight type string, I'd pad the loops up real good and fat.
Cool little bows. Mine never seemed like a speed demon, but it was nicely made and shot smooth for a short bow. I liked it a lot better than the Kodiak Mag I'll tell you that.
I haven't got a clue on brace height, but string length should be around 4" shorter. So a 48" string should get you started. Id get a Flemish style so you'll have a little more range to twist it up and tinker with brace height.
Post up some pics!
