i have been shooting the same arrows with 175,200 and 125 gr points. i cant tell much difference between the 175 and 200 but the 125 went nock right. i still cant get the nock high out, but i will get some shafts put together and then tune the fletched shafts. i am going with the 200 gr point as there is a wider array of heads to choose from. it is still throwing the shafts pretty quick for a 525 gr arrow. now i just gotta get used to shooting a shorter arrow and not having it in my field of view as much as i did a full length shaft. hopefully i can try my new set up on a hog to try penetration very soon!
