Totally agree with Ken, spade end hooks are my first choice for size 8 hooks and smaller. I also like to whip a size 12 or 14 just above the main hook using the Snell knot. I reckon most of my fish are lip hooked on the top hook.
The best knot for spade end hooks is the snell knot. There are a few ways shown to tie it but the simplest and most effective is shown in this link

I've never had one of these knots fail but do make sure to keep the line wet. I pull mine tight under the tap or hold the hook under water.
