I’m heading to ID in Sept. in search of my first elk. Will be using my new Centaur LB @46#s. Single bevel Cutthroats. Should do the job if I do my part.
Try Saunders NPV. I used to use the Platinum but like you had poor results on aluminum. My last fletching job with the Saunders looks good. There are a lot of others out there who recommend this product.
