What are you going to use them for and when?
Will you be using this tent by yourself or with another person?
How much kit will you have with you when you camp?
Do you need the same set to do for spring/summer/autumn/winter?
Do you plan to do multiple camps of short or long duration, or just go to the fests/moots?
Will you be using the set in the UK, Europe, Asia, America?
Flatland, wetland, desert, mountain, woodland?
I think you're getting the gist of it - tell us a bit more about what you plan to do with your new sleeping bag and tent, then maybe we can give you some relevant advice.
