If I were choosing between those two in the 100 grain weights the sidewinder would win. I like the design of the steel head better but only on the 125. IMO the 100 grain head has the tips of the baldes far too close to the tip of the furrel which does not give the tip a chance to burry into the hide before the blades start to deploy. I just worry about the head kicking off on a quartering shot with the 100 grain steel head.


But to be perfectly honest with you I wouldn't shoot a mechanical head if I were only producing 59 foot pounds of energy. At 30 yards the arrow will only have about 54 foot pounds of ke. YOu will probably be ok but I would rather NOT take the chance.
