I shoot arrow dynamic trad lites with 160 grain snuffers and a steel broadhead adapter for a total point weight of 260. I would like to try the magnus bull head but they are only available in 125 screw in. My arrows are already setup with inserts glued in. My question is can I make up the weight difference between the two points by adding weed eater line to the shaft so that the two arrows weigh the same. I know that the spine will be different (the arrow spines well with both points) so that is not a concern I would like the trajectory of the two shafts to be the same. Can this be accomplished? I am open to ideas but would prefer not to change inserts.
