You probably do not need new rods, just keep in mind that the polish chrome rods(the older they get) will play slower than the hardened chrome rods, it is ismply an adjustment you have to make from old rods to new ones unless you want to spend in excess of $300.00 for a new set of the heat treated rods. A part solution would be to buy just the shooting rods(4 in total).
As far as the half moon crack by the goalie opening, it will eventually blow out. If you have a wood router, white laminate, a heat gun and some cotact adhesive it is an easy fix. If you do want to attempt to fix it let me know and I can go into more detail for you.
