I was using carbons; X-press I believe is the brand. I always fletched my own aluminums and actually have about 2 dozen freshly fletched with a 5” Right helical that still need cut off. Those are xx78 Superlights in 2213’s. Total length is around 25”s. (I do have a few pre-made just to shoot)
I’m down to 4 carbons now, the other two I had shot the nocks off practicing and demolished those. They just don’t take a beating. Either they are straight or broke.
Anyhow, I know my bow shooting those aluminums get better penetration b/c 2 weeks prior I shot my carbons (with field points) and the aluminums side by side and got at least 3-4” more penetration in the Block target with the aluminums. It just makes sense that a heavier arrow will have more foot pounds of energy down range. I shot 75 pounds from my dual-camed High Country, but this Solo-Cam shooting carbons just doesn’t seem to have the same energy. Of course we’re taking about a 37” bow vs a 32” bow too.
Anyhow I’ll be eating backstraps tonight, but I thought I’d just share that experience I had in case anyone cares

ha ha. Hopefully I’ll have a better story in 2 weeks when I shoot the next PA record
