The tent arrived this afternoon but too late for me to pitch it on some available office floor space at lunchtime. I did have enough time, however, to whip out my postal scales and weigh the individual parts. Very sad I know but it does confirm that the actual weight was 1750g all in with the inner, poles and fly adding up to 1500g. The tent was supplied with 12 Y pegs that made up two thirds of the 250g over the weight of the inner, fly and poles. Having owned a MHW tent before I knew that they are supplied with optional guylines and guying points for which they supply pegs, so swapping these for titanium ones and working out the optimum number of pegs needed is an easy weight saving.
Time to get it home and have a play.
