Depends how you want to use it or how long you plan to run for. For long runs I use the "Raidlight Olmo 10" with 2x "camelback podium" bottles (c.700ml). This serves me fine on c.30mile runs and I could get away with alot less if I wasn't practicing nutrition for longer runs. I use this set up because I can easily refill or swap my bottles if necessary if I need more.
For shorter runs I'm experimenting with a "camelback delaney fit" waist pack with 1x podium bottle. I'm struggling to get on with waist packs but am getting used to it slowly. This again has the advantage of easily being able to top up or swap bottles if I need.
I used to run with a now well out of date camelback hydration bladder with just over a litre capacity. TBH it was probably the most comfortable of the lot (although the Raidlight is also very comfortable) but I ditched it because refilling a bladder during a race much less convenient than swapping bottles, but if you don't anticipate needing to refill then any of the lightweight camel back ones will also do a good job.
See, I've always had a dislike of waist packs. But then, I'm a heavy sweater and carrying a pack on my back seems to make this considerably worse. I have one of those running bottles that looks like this http://www.marathonchallengemalta.com/Running%20bottle%20P39.jpg that takes about 400ml, which is fine for an hour. It's when I get over the hour when I need to start taking on considerably more fluids, carrying any more by hand is a pain, as I found today. As for distance, recreationally I'd like to be able to run a half marathon with ease. I don't think the question of speedy refilling is going to be an issue for me, can't see myself ever running competitively. I think I'll have a look round for a minimalistic camelbak with 1.5 capacity and give that a go.

Thanks for the advice.
