My experience with metal rods is 1. aluminum-to me it's just not right 'I have a ''unbreakable ''rod but that is for staying at home ,it's not PC,even when hunting I strive for the experience of traditional ,if my ancestors were saddled with the problems of wood and suceeded than I can use wood with its problems ,in the event of woods failure than I am forced to solve a problem that an ancestor had to solve[or go home whipped , whining..or...captured uhh?] I have made my own in a pinch while out hunting when a rod cracked while loading up ,hemlock worked really well and I had it finished by the time I needed to reload[I got a doe] 4 hours later .
.2 Brass works well and is pc but adds weight and tends come loose due to momentum so I stick to wood .Wood will break sometimes when you try not to use a short starter,did that twice.
