I'd keep the fists until like 45ish and then replace it with crab hora or peiste cesti.

About eternal shade....its just overrated. Any natural upgrade would make up for NM drops...You can move to Velveteen Tabard, Scouting Jacket and later on Toad Harness with no fear of doing something wrong.

Look the fists + shade:
Atk 113
Acc 142
STR 3
DEX 6
Eva 28
HP 10

Now i'm getting Tabard + Crab Hora (you can just go straight to toad too...i'm getting tabard because its at optimal rank for you).

Atk 130
Acc 146
STR 4
VIT 5
Eva 31

So, even with all their bonuses, they don't really are worth using past average equipment rank range, which is 10 ranks above of it.
