I would be interested to know how you go. We have found that they block quite fast as soon as you add more than about 40 grams of hops in a 20L batch.
If your kettle fits this false bottom this works really well for large amounts of hops:

We have lots of people using the
BrewZilla/Robobrew units and this false bottom still works well and doesn't seem to block even with 100grams or more of hops in a 20l batch or more.
With that said some customers seem to like the helix, it's just not my favourite solution.
