I found with my enclosures that i got best results using both cloth/weave and csm.
The infusion made it easy to go super heavy with the glass and the layups were more often than not upwards of 2000gsm.
I believe most of them were
200gsm cloth
450gsm biax
450gsm csm
450gsm biax
450 gsm csm
450 gsm biax
200 gsm cloth
I also added additional layers of csm and biax in the flanges for more bulk there.
