Shape doesn't matter much to me.
But mine are: D'Andrea PRO-346

Don't know about those other numbers.

I use a Blue Chip STP 40 on my Collings MT mandola.

I use a green Dunlop .88 Tortex -it was standard shape but I have sharpened it up. Next time I might try it in a Jazz III shape.

After many changes of mind I think D'Andrea Pro Plec 1.5mm give me the woody dark sound I like.
Their cheap enough to just give it a try.

I use a Primetone 1.3 but it really depends on your instrument, its setup, what strings are on it, what style of music you’re playing and what you feel happy with. It’s largely irrelevant what others...

I don’t know, the advertising I can find does not mention a truss rod so perhaps not?
It does have a ply top though.....
