I've got a 60litre with a 15L detachable daypack. It doesn't look that big for a 60L though and i dont plan on filling it, it didnt cost me that much as it was on sale when i brought it. But if it ends up being too big still i will just ditch it and buy another one out there.
But yea, smaller the better. 45-60L ive heard is about average.
Does anyone know the real levels of begging/harassment to use services like rickshaw's? On many sites it says levels can become unbearable around the biggest cities especially where tourists are expected to be.
I've gathered the best way to deal with this is to simply be firm but humorous, however can imagine the humorous part could become hard if you have a large number of people following you bombarding you with offers with little let up. Is it really that bad?
Also is it possible even in these areas to find less ..... enthusiastic, rickshaw drivers for example. Or is everyone the same, due to such fierce competition? As an example i would be more inclined to use the services of a rickshaw driver who is not trying to ram his services down my throat, or is it not as bad as that?
India is the great country. You will find many differences in culture and language. I had visited India last year and had a great experience of touring in India.
