In reply to Midgetgem:
I wear both. Indoors I prefer my LV and outdoors I prefer my pinks. I find the pinks are too stiff for indoors. (I also prefer the velcro fastening on the LVs which makes them easier and quicker to get off between routes indoors - I have shorter rests between routes indoors.)
You have to find what works for you. Everyone has their own preferences/reasons for their choice of shoes.
