If you have Shun 5/5 it is better for outside.
Hi wins by miles inside still.
Heres my Shun WS set:
<main>Kikoku</main> 99
<sub>Arisui</sub> STR
<ammo>Bomb Core</ammo>
<head>Oce. Headpiece +1</head>
<neck>Light Gorget</neck>
<lear>Brutal Earring</lear>
<rear>Jupiter's Pearl</rear>
<body>Toci's Harness</body>
<hands>Iga Tekko +2</hands>
<lring>Epona's Ring</lring>
<rring>Rajas Ring</rring>
<back>Atheling Mantle</back>
<waist>Thunder Belt</waist>
<legs>Byakko's Haidate</legs> - 4 crit
<feet>Dilaram's Sollerets</feet>
Any idea what moonshade Atk 4 and TP Bonus 25 does against Dex in that slot? Curious. I recently 99'd my kikoku and trying to brush up on my set, its pretty similar to yours except for the earring. From what I have been reading the atk penalty gets modified every 100tp?
