I challenged myself to become very efficient with a compound bow,not to hope I make a good shot. If you want to use a crossbow so be it, I don't see the 10x more effective angle but in the hands of someone who is not a very very proficient shooter with a compound, yes it would be more effective. Just don't forget that just because it has a trigger it means you can take the shots you can with a firearm. Because you can't.
