The good thing about blade tape is you always know when it is coming off. Shaun, from the days of taping Bell 47 blades (almost daily) in the Australian Out Back - it peels off as you describe from the trailing edge. The aussies would also put hysol on the TR blade tips to stop the erosion.
Helilog56... like...what would you know?
We never used blade tape in the interior - not wet enough like on the coast where the loggers are pulling wood. Blade leading edges seem better and I think pilots are now more aware of adverse erosion conditions... like hail.
