for me it would have to be the standard knotless knot hair rig for bottom presentation. id use a wide gape hook pattern for this and n trap soft hooklink material, i like to use a kicker or small piece of heat shrink on this hook as it turns much more aggressively. for my second rig it would have to be Darrel pecks pop up rig, its the most simple pop up rig you can tie (easily found on a google search). for this rig i would use a choddy hook and n trap stiff hooklink material.
for me the 2 hooklinks above cover just about any presentation i need to, and tie my other favorite rigs. as for the hooks, the wide gape pattern has landed me more fish than anything else, although i have to say that i have played with the krank hook and im a big fan of that also. as for the choddy hook for pop ups, ive found nothing that sits better. a note on the wide gape, i used korda kaptors first, they very the sharpest hooks ive had straight out of the packet but i did have more than a few bend on me, i now use the wide gape x from korda, ive never had any issues with that hook.
