I know, I know... Another Drow Rogue? Can he BE more cookie-cutter?!

I decided to follow Tihocan's guide to making a Dark Blade Rogue and I have a few questions I was hoping you guys could help me with.

I'll start by saying I'm not too fond of using Rapiers, so I'm intrigued about the variant build mentioned under Tihocan's variant list about going the STR path rather than the Finesse path and using a khopesh as a main-hand weapon over the rapier.

If I were to go this STR path as a Drow, I'm not entirely sure what I should do with my ability points on creation, but I was thinking something like this:

STR: 16
DEX: 15
CON: 12
INT: 16
WIS: 8
CHA: 11

The 15 DEX is so I may take TWF at level 1, then grab Khopesh Proficiency at level 3. I threw the last point into CHA for a bit of help with Diplomacy (along with finding a +1 CHA item to bump it to 12 eventually), as I wasn't really able to throw it into anything else other than DEX, but I could increase DEX with enhancements. Then I would continue to raise STR every four levels (with granted ability points).

I don't really know. What do you guys think? Maybe I'm just better off going with Weapon Finesse... (But I don't like rapiers...)
