I keep hook changes simple for 90% of my hook changes I use ST36 1/0, 2/0 or 3/0s. There are probly more people that can roger up to this better then I can, but this works for me. For 10" TT I use 3/0 in the front and 2/0 in the rear. On 8" I use 2/0 in the front and 1/0 in the rear. And on the 7" I use 1/0 front and rear. For punkers 9" 3/0s all around. 8" punkers 2/0s all around and 5 and 6" punkers 1/0s all around. I have never thrown a Sellcraker or a injected punker so I have no insight on that.
