Hi all
I was back in Japan last week and came across these magnesium v-stakes:

After a bit of checking around it seems that most aluminium v-stakes weigh about 20-23 grams, titanium v-stakes are 10-13 grams whereas these magnesium v-stakes are …. 8 grams (and 17.4 cm long and 14mm wide).
At about US$3.80 per peg they also seem to be roughly the same cost as the titanium v stakes around.
