Good CMW dex weapons?

Hey, in NG+ with my PvE character at the moment using a CMW/Dex build. I've decided that my Painting Guardian's Sword just isn't the weapon to me (the short range can be VERY frustrating in some situations) and am currently trying Riccard's Rapier which I quite like, although it's also sometimes a bit frustrating in certain situations as it never moves vertically, it only thrusts horizontally.

What dex weapons do you guys normally go for with buff based builds? Just to clarify it's heavily based around CMW/Power within/Lingering dragoncrest ring.

Edit: I only have 16 STR and don't really want to go higher, just to add.

Ricard's Rapier
Uchigantana
Balder Side Sword
Laito
Flamberge
(Great) Scythe

My favorite weapon overall to buff is probably the Falchion, but it isn't as versatile as some of the others, like the Balder Side sword or Longsword, etc....

Washing pole, but everyone will hate you.

Falchion, that thing destroys with a buff or no buff.

Ricards Buffed with CMW is absolutely deadly in both PVP and PVE

Another weapon I really like buffed is Iato.

Falchion is probably the best choice though, buff it, lock on, and let an opponent get close, if you two hand it and keep swinging away you'll never get backstabbed, and you'll destroy your opponent.

16 str is enough for winged spear isn't it?

I second the Falchion, it is one of the best weapons in the game buff or no buff. You can win fights literally just by spamming r1. It breaks 76 poise in what seems like 3-4 hits.
