Given how much time (and/or $$$) it costs for a rod R&R, I'd always just pony up the money to buy new rods, preferably better than stock if available. And it would go for ANYTHING. But that's just me. Get it done right the first time. I respect experimentalists who make their mistakes, learn from them and let others learn from them too. Wherever possible though, I just try to avoid making mistakes from willful acts in the first place.
