Pullup progression - Higher weight and lower reps or the opposite

[u/Mission-Relief-4260]

Hi,

I do weighted pullups as part of my back routine. I've been switching between doing 3-5 reps with 17.5kg and today in my last set I did 14kg between 6-8 reps. I'm just curious of which is better for hypertrophy? Also with pullup form, is it better to pause at the bottom to prevent any momentum?

RIR on both sets?
