I am looking at getting some new arrows for the upcoming months and have narrowed it to the Carbon Express Maxima 340's and the Gold Tip Pro Hunter 5575. My question is how do these arrows compare to my current ones which are the PSE Radial x-weave Pro 300's? Also I would like to keep the arrow weight down to about 8.2 gpi which is why I chose the maximas and not the maxima hunters, but the gold tip chart says the 55/75(which is the one i will use) is right on the edge of being too lightly spined with a 100 gr. head will I be okay with this setup or could I cut my arrow down to like 28.5" and be at the right spine?My specs are29arrow lengthand weight 65lbs.
