Full suspension or hardtail for offroad in South Wales I mountain bike in the hills of South Wales. I am due a new bike and have been riding a 17kg full sus for a few years now. I mostly ride 15-20 miles every week (hopefully more when the summer arrives) of moderatley technical terrain and the occasional trail center and big ride. I'm of average skill and a fairly hefty guy at 14.5 stone and often give the bike a good few knocks and abuse.  

I cannot decide whether to buy a full suspension or hardtail bike. My budget is £1000. There are a few half decent full sus' bike around for under this with the current sales. Also a load of really good hardtails. Can anyone point me towards something suitable?
Yes there are a few full suspensions in that range, they will be heavy, and mid to low level parts. Saving a bit longer and waiting (hard i know) Maybe £1200 - 1500 would get you much further.  

Your current bike is 17kg. a £1000 bike may only save you 1 - 2 kg. A nice hard tail within your budget would be very light (12 - 13kg)

Another option would be a 29er. the bigger wheels, and high volume tires will really help with overall comfort and capabilities on rocky technical trails, while still being fast and lighter than the full suspension in that range (but likely still 14 - 15kg)
