Another factor that helps is to use the thinnest wire hook you can without compromising strength. You don't want them to open up but you want the penetration to be easy and the hole to stay small thru the fight. Some of those very expensive hooks give you the best ratio of strength to wire diam via high-end materials and chemical sharpening, thus are very expensive. The cheap SW hooks are made of crap metal and to get strong hooks you often have to go to a wire diam that is ridiculously heavy and barbs that are damn near impossible to crush, shaped like an anchor barb.
IMHO it pays to use the best hooks you can buy - TMC, Daichi, Gamakatsu, etc. Well worth the $ in the long run.
