Ive shot 9 deer with them in the past 3 yrs. Four with the 3-blade and 5 with the 2 blade. Id go with the 2blade because to me theyre more durable and easier to replace blades on. Ive had only 3 that didnt get a total pass thru. 2 of those were spine shots and the other was an extremely hard quartering away shot were the arrow pretty much went threw the whole deer. I shooting 382gr @ 302 fps. Havent had a blood trail that i had to actually stop and look for yet
