Just ordered a Parker Cyclone. Being very new to crossbows have a few questions. After reading all the posts I am a little confused and need some clarification. Arrows, seems that most carbons are the choice. Broadheads, too many suggestions. Although 2 blade seems to fly better? Total arrow weight for this crossbow should be 425 gr. FOC seems to be important but what total gr as opposed to overall arrow weight? My hunting distance is an average of 30 yds some shots could go to 40. Any advise would be greatly appreciated.
