Im not that good, I saw shiny CONV and had to use it :/
I hope this is insiightful, as it is not ment to be demeaning or hurtful and is just something I noticed.
I personally suggest things like inwr, crmc, inst, and bcln to help fill out the majority of the alloy as they can actually provide extra strenth to the alloy even in the presence of conv.
conv is fine in alloys, but this one falls apart completly without it, since the other matirials provide none of the strength here. It's a good idea in principle, but you need to find better combinaitions of materals to use for the rest of the alloy because the ones you are currently using are not pulling their own weight.
