hmm it's already at the 3rd notch wouldn't that make everything too rich?

That said.. I've tried adjusting the air screw and can't get rid of the hesitation, it pulls hard after it splutters for a bit.

If you have turned the pilot screw clockwise to richen the low-range mixture and that did not solve the hesitation, then moving the clip on the needle to the 4th groove should be considered.
However, you have left out some information. You did not say at what position the throttle was in at the point when the hesitation occurred.
If the throttle was between idle-1/4 throttle, then the pilot system needs attention; if the throttle was at 1/4-3/4 throttle then the needle needs adjusting; if between 3/4-wot then the main jet.
Did you take notice at what position the throttle was in when the hesitation occurred ? If not, then you need to.

The hesitation occurred from 1/4 - 1/2 throttle. I've put notch of needle on 4th and it's got rid of the problem. I get lots more 'pops' on decl but I quite like that.

So now I've got a #17 pilot, screw turned 1.5 turns out, needle at 4th notch, now I think the main jet needs to go bigger as well.. seems to struggle for a bit at WOT

Still popping on decel ? Is it loud like shots ? If so, then when completely warmed up continue to tune the pilot screw by turning it IN to see if that will improve its running ...increasing the engine rpm and result in eliminating the loud shot-like popping.
If the popping is not shot-like then you are ok.

For the main jet, you said it was struggling a bit. Is it stumbling as you near full throttle or is it just loosing power and run out of breath ? IF stumbling then go leaner, but if just running out of breath the go richer.

It's kinda cool.

Popping and crackling is not a problem, it just sounds goooood on decel.
Take you main jet up one size then and see how it responds when wide open. If it runs strong all the way out then you are good. If it bogs down at wide open then go back down in jet size.
Sounds like you are getting close dude.
