as much as I appreciate being mentioned I’d like to say that I haven’t ran stark nor seductress after I finished them in my first ever 4 cycles two years back.
Ever since I had been exploring each sub in question of 2/3 cycles and had benefited greatly from every single one of them having long lists of results by each month more and more.
I never really embodied any of the subs fully (even though I embody them quite a lot and quite quickly thanks to my great flow) but I reaped it’s fruits greatly to my satisfaction to move on.
I would encourage anyone to go with any variation of subs in their custom as they’d like. I know subclub delivers subs so breathtaking, you will reap their out of this world results before you even realize it.
Yes if you only now start running your first khan custom, someone who ran it for years before you will be ahead of you
but that doesn’t mean your results will be lesser. If anything, the beginning of the journey always feels the most world changing and exciting to me 
and even if they are ahead due to them sticking to something for longer than you, who cares! This isn’t a race and as long as you keep your listening schedule good and make effort to flow with your script well by hydration and positive self affirmations along with action taking, you are on your own path to conquer the world and nobody can stop you!
you will always get results it’s just about being able to spot them yourself
I see your point though! Peeps who stick with something for very long are out of this world beings and they get to tap sooner into the deeper and deeper knowledge and use of their subs!
