"My opinion is that the woodies will fail under continued stress of these high force manuvers, and you probably wouldn't see the stress cracks due to the covering before it is too late. You could fly them for awhile I suppose

Get real Man,
I have always used woodies, from the time I started in the early eighties and have never seen a wood blade crack from stress. I have also seen the best of the hot doggers using woodies before all the composite blades became the rage, again NO STRESS BREAKAGE.
The composite blades just plain fly better, but don't listen to this stress crack crap.
