Hey guys! I went and got my broad heads. Magnus 2 blades. I'm still new to our sport. Been shootin almost a year before I ever put any thought into it. I shoot 4 inch vanes. I got some free 2 inch blazer vanes. To try out. Cause I do have fairly light arrows. I'm not gonna hunt with them. Cause I'm set up how I wanna be but I did have a old arrow so I fletched it to try out. Honestly. What's the difference. Does anyone think 2 inch vanes are better than 4 and if so for what reason? Only thing different I ever do is play with arroiw weight and keep my sights dialed for my hunting weight. Ok. Enough said bout that, secondly. My friend swears up and down BH must be inline with fletchin. I think this is silly and a matter of prefrence. Also I plan to get a new string after season. Any one got any advice?
