Coarse Grinder & Waterpiece / Bong

Hello everyone,

TLDR: should i get the BCG or Aroma 3 for my arizer solo 3V2 Recommendtions for waterpieces, any trustworthy shop for custom made ones? (Preferably one which isnt a pain in the ass to clean)

I am happy owner of the Arizer Solo 3 V2 and absolutely love it, however my current grinders grind is very fine which is not ideal for the solo 3.

After doing alot of reading online i decided i wanted to buy myself either the brilliant cut grinder, or the old mate aroma 3. I couldnt really figure out which of the grinders would be better / have a more coarse grind, so maybe anyone can help me out on making the decision.

Also i decided to look for a bong / waterpiece to hook my solo 3 up.

So far i have been checking lees table top bongs and also vape north devices, and found some interesting models. However while doing my research i figured why not get myself a custom made waterpiece? Anyone here can recommend a good shop for ordering a custom made one?

In case someone has suggestions for nok custom waterpieces i would be open too!

I live in Germany if that matters.

Thanks already in advance for rep
