[QUOTEIt's tough for me to comment on fix blade performance-I've never killed an animal using one. ][/QUOTE]
My musk oxen was killed from 30 yards with a second arrow delivered from my Super Short. The first came from a traditional 58 pound takedown longbow-using a 525 grain arrow tipped with a 150 grain Snuffer.
Last I checked, the Snuffer was not a mechanical. Just bustin' your chops a little. I can't out do ya with on anything else, so I gotta take a shot when I get the chance.
BUT, it's obvious that you and your ssiter have had great success using mechanical broadheads. I've had one mechanical failure with a spitfire and I guess after once, I just can't put my trust in any of them for big game, although like I already stated, I do use mechanicals on smaller framed critters.
Good luck this coming season. I've said my piece here and movin' on.
