my simple ab routine
 

cable crunches 3x20
hanging leg raises 3x as much as i can (if i exceed 15-20 reps ill add weight)

done after weights 1-2x a week

is that good enough?

i also do deads, squats, weighted chins and dips which i believe uses my abs

How do you add weight to hanging leg raise?

IW

0.25kg ankle weights

Don't neglect your obliques. Any sort of twisting exercise shall do - medicine ball twists, russian twists, cable wood-choppers, etc.
Also keep in mind that you don't always want to go heavy with weighted ab exercises. You're trying to build a small, lean, tight core... not a thick bulging one. It'll take away from your V taper.

Exactly what I was thinking!

Those exercises are fine. Just remember that visible abs come from low body fat, not from ab exercises. But it's fine to train the abs and strengthen your core muscles.
