Its not about my personal consideration, but game mechanic. If you wear more meva, but you have still floored magic evasion then that meva gives you nothing.
Wakido vs Kendatsuba +1 is +22DEF +3VIT -1HP. I wouldn't call that significantly higher def, vit and especially HP :P
Nyame path A is by far superior choice, but it's a matter of choice to reduce your hybrid damage potential for better TP set. Nyame path B has Double Attack which is generally almost invisible stat in SAM TP set focused on Zanhasso, because gain from DA chance evens out the loss from losing the Zanhasso chance, so path B Nyame is strictly a defensive option in TP set.
