After all of your useful comments I finally purchased the Shangri-la 3 which should be here by Monday. Thank you for your help!
I have just one more question regarding this Shangri-la 3 quest! Being a British user and concerned about the cold, the wet, and the damp I now find myself deliberating very hard about the various options INSIDE the tent.
Mike Reid in one of his posts about the Shangri-La 3 mentioned that by pegging out the dedicated nest seperately to the tent one could easily create a vestibule and prevent rain / dirt when entering and exiting. This clearly addresses some of my issues. My question then is whether you feel this is a better / simpler option than going the other (quite circuitous) routes such as half floors, self made nets,the SMD serenity net etc?
I know the full nest compresses to a smaller pack size than the Shangri-La 3 tent itself and so room in the pack is not an issue (I have really done my best to completely shrink my kitchen explore multiple use etc and so I have the space in my pack). But does it REALLY make a huge difference do you think (in practical terms) whether I'm carrying a half ground sheet / SMD serenity net combo or simply the Golite dedicated nest? I mean i'm not an ultralight obsessive (although I might be getting there). And finally I'm thinking that maybe the full nest for British use might actually improve warmth with the full floor covering – might that be true? I also think that in dire weather I might also feel cosier.
In many ways I have almost convinced myself that the Golite dedicated nest will be the easiest and most practical solution for me but before I go ahead and purchase one I really would like your impressions (and especially Mike and others who have used the nest).
Thanks again!
