I, too, used these in France. Never lost a fish yet almost all hookholds were released in the net. As stated, these are SHARP hooks! I used the straight points in size 4 and they were ideal.
I'd add that I've just had a long weekend on Horseshoe Lake, the Carp Society's headquarters, using the same hooks. I blanked but one of my fishing buddies had a PB mirror using identical hooks in a very weedy water. I'd be happy to commend the hooks to anyone.
