mine is down to 90g. shaved on the outside and drilled some holes - 4 bigger ones in the middle and 3 on the left and right. they vary from 20mm to 9mm getting smaller towards the front, right and left side...
as my ass doesn't like the hard pure plastic feeling, i started to re-pad it with 2 layers of 3mm foam; 2 stripes, one on the left and one on the right whereas the second layer covers the whole saddle. as the white leather is still in ok condition, i'll re-use it (not to mention the look...)
saddle w/out leather and padding: 90g
new padding: 6g
leather: ~12-15g (not sure about this. it's not cut to fit the new shape yet. right now it's still 19g)
i guess, i'll end up at <110g which isn't superlight but quite ok for a padded and covered slr
*edit* anybody wanting to buy me a digicam?
