went to Afan last August and it poured down :o( I wasnt prepared for it and was ill equiped and so left early aftewr 2 days. It was only 1 month into my return to mountain biking after 20 odd years off smoking and getting fat and unfit. Am going to return this august for a long weekend and hope the weather is better, but if not (it is Wales after all) I will be better equiped to deal with it, more kit, better kit and also a higher level of fitness, motivation and tolerance of rain and wet clothes.

I hope there is enough to do there to keep me going for 3-4 days??

Last time I did w2 on first afternoon and skyline the next day but even that was only a a few hours.

I notice there are a few more trails now but is there enough off route stuff to keep me going for 4 days?

Check out http://www.mbwales.com website. All the trails are listed there. You know how quick and how far you can ride. If its not enough then you have Cwn Carn nearby by too and lots of natural riding too.
