RE: Broadhead weight
as far as 125's to 160's -- the switch was done while shooting my SQ-2 b/4 getting my switchback xt. i noticed very little difference. i have a pro-shop friend that gets the 160's to fly straight at 40-50 yds w/ 2" vanes. when i started trad , i was already shooting 160's.3 rivers has 145gr tips to try. i can't find 160gr so i added 3 5gr washers. i would reccomend the woodsman 150s. you'll have to adjust yourself forthe dif since you'renot shooting sights.
