I have recently go a person trying to sell me some arrows for 50.00$ They are GoldTip Expedition 3555 arrows. Right now I am shooting 70 pounds. I have been thinking of droppin the weight on my bow to 58 to 61#. I have a 29 to a 29.5 draw length. I shoot a 27 in arrow. So goldtip size chart says i can shoot the 3555 arrow on 58 to 60some. Would I lose all that much speed if i lowered my bow to 58 to 64 with the 3555(500) from the 5575(400) at 70 pounds??Im more accurate with less draw weight even though i weigh 235 pounds and am about 6 foot tall? I can hold the 70 but cant hit consistint as on lower poundage.What would you do??
