Cha items for selling. Worth carrying?

[Tobius]

So I have 5 pieces of 'armor' that has cha on it that I put on for when I sell.

15+5+5+3

Historically I had more slots then carrying capacity, so this was justifiable, but now I can carry plenty, and I am looting more expensive shit.

Does the increase in selling price make it worth having 4 less items every haul?

I'm starting to doubt it.

For basis of comparison:

Vendors offer me 7p 6g 9s 9c for embroided black sleeves with my fighting gear on.

Vendors offer me 7p 8g 5s 9c for embroided black sleeves with my charisma gear on.

In fact from this it's starting to seem obvious now, but can anyone clarify for the record?

Alternativly I can keep the cha gear in the bank and put it on when I sell. Would that be the most optimum?

Additionally what does cha cap out in terms of affecting vendor prices?

Thanks,

- Toby
