Most aluminium shafts are about the same. Problem with your setup is they are going to bend just about every time they crash. Nylon will more often or not hold up on hard floors the best imo.
Your board is VERY old and that means its probably almost like concrete. Allot of people will tell you to spray water on it but that only helps to keep a board hidrated. Once it dries get rid of it. For 60-70$ in a real game shop you get a super nice knife blade board that your darts will sink into.
After you make sure your gear is good it helps to be able to hit the board:)
