I pinch em religiously here, as soon as I head east or west I fish with barbs... One exception, I kept dropping fish one year in a tourny in SK, we were fishing on the deep side and I think I wasn't driving the hooks hard enough... Long story short, I pinched them and put more fish in the boat barbless than I did with barbs on... Not sure if there is ever a measure of how much (if at all) harder it is to drive hooks home with barbs...
Only time I wish I could use barbed hooks, is topwater smallies here... All my other presentations I have tweaked or altered the setup to make it work in my favour, for example Lindy rigs are now 99% of the time a circle hook matched to the bait, miss the odd hookset, but once they are pinned they are pinned usually...
I do have to agree with Mike on this, in this province with the broad spectrum of anglers and the typical uneducated mishandling of fish or misuse of technique, Barbless is the way to go...
