Have you thought about a carbon fibre tripod, less than 2kgs. I've got the 055 and it's as heavy if not heavier than the 190
The 055 is significantly bigger and heavier than the 190... I have both. Bought the 055 first then decided that I was fine crouching down a little to save the significant weight difference when hiking so got a 190 (carbon) a few years later.
At 6'2" the 055 was fine for me to shoot without crouching and without using the centre column IIRC.
