I hear you, but it's not like you can't deactivate Tassels when you need to do some soul generating yourself.  
The only reason I have used Cov w/Palestine is if I am using captures on the defense.  That way I can get lost souls out of my LoB if I need to.  If you are going to use some Egyptian capture cards (of which there are a few) I would go with Cov w/Palestine.
