I've taken a few "raking" shots, but there was always an offside shoulder in my sights. Funny thing is I've never lost much meat to that shot. Onthe other hand it's not always easy to clean up either.
The only reason to take the straight on THS is to anchor an already wounded animal. If I get that shot opportunity and he doesn't have a bullet in him---HE WON! He gets a PASS.
