Like everyone else has said, if you properly shaft/nock tune your arrows, you should have no problem. I have the 100g wide vented, and 125g solid single bevels and both group amazingly well. I practice out to 100 yards and notice no difference (within my abilities) in grouping. My realistic ethical shot range is about 70 yards. I shot the same head in practice 5-6 times a day and continually touched it up on a sharpening stone since june when I first got them. This season so far it has been through a Turkey at 51 yards, and a large doe quartering hard towards. The doe entered through the neck/trachea, through 2 ribs just off center of the brisket, continued to slice into but not through multiple ribs, and ultimately through 2 more ribs on exit. One crazy thing I've never seen before this is, where it cut into ribs as it traveled down the inside rib cage, it made a cavitated pocket of blood that was trapped between the hide and ribs. The doe made it about 15 yards and went lights off and tumbled down the hill. The head is still in excellent condition and I plan to continue to use it with no hesitation. They are expensive, but you get what you pay for. I will never shoot anything different. The solids are def more quiet than the vented, but IMO unless you're hunting really skittish animals that are aware of your presence at long range, it shouldnt have that much effect. They're more likely to respond to the initial sound of your bow than the flight of the broadhead
