Have had much the same problem with B T Raptor hooks myself. Went from using Korda barbless hooks to barbed B T 's and have had problems missing runs and losing fish that "seemed" well hooked or runs than "seemed" unmissable.
Have probably had worse results with barbed than barbless hooks since i changed !
Do not think boiling water is the reason, maybe just the way the hook is curved or how sharp the point is ?
I for one shall not be using them again, have lost all confidence in them.
Thats not to say they are a crap hook or anything, just not for me.......
