camera/lens belts....? Which one do you recommend?

[haring]

I would like to keep my lenses on my belt while I am shooting. I have found 4 belts I like.
Do you have any of these? Which one would you recommend?

- I like the wider/thicker belsts hoping that they don't hurt your back... The thin ones may hurt my back... Any thoughts?
- Also, I would like to use any pouches for the belts... Some only accept their own brand pouches which is very limiting...

1. Lowepro S&F Deluxe Technical Belt (L/XL) B&H # LOSFDTBLX MFR # LP36285

2. Lowepro S&F Light Utility Belt

3. Think Tank Photo Pro Speed Belt V2.0 (Medium / Large, Black)
4. Think Tank Photo Steroid Speed Belt V2.0 (Medium / Large, Black)

5. Think Tank Thin Skin Belt V2.0 - L-XL-XXL

Thanks!

Nobody using these for event or wedding photography? I guess they are not as good as they look.
