I use CA for everything and even the firewall for up to 1.20 size.
If you can't make a perfect (no gaps) joint, then don't use CA, if you can make a perfect joint, then CA is as good if not better then anything out there.
My 33% GP Extra was done this way except for the firewall which was also pinned
mama-miea you gotta be serious CA all the way!.. i gues only laser cut kits will be ok to use CA all the way i geusss..
