I can say, the goblin mini is fantastic, but the main thing you will probably have issue with is wicking.
Honestly, I find less is more, you just want to press it gently so it is resting on top of the juice flow channels, don't actually tuck any down there, if you do I find it either leaks, or if you pack more, dry hits.
So, essentially wicking it will be the hard part.
But, just rest it on top, apply some juice to the wicks and then you can kind of stick them there, then happy vaping!
Also, don't be afraid to try a single coil build in there-it is great with singles as well as duals, you can use less power if that is your thing
.
Hope it goes well!
