i change the trebles for owner trebles st66 and crush the barbs down.
i personally am not a fan of the single hooks on poppers for gts (what i target where i am) as i find the hook up rate is significantly lower in my limited experience, but in saying that, i have missed plenty of strikes using two trebles also.
most poppers that i use come with factory trebles, therefore i assume that they swim the best with trebles on them instead of changing the balance with singles etc. just my opinion and i know lots of guys who think otherwise.
fish seem to be able to shed the trebles on bust offs as i have seen the popper floating immediately afterwards and gone and retrieved it with the boat.
but i am not fishing for kingfish so it may be totally different.
