I think once you feel the bulk of a 1.1L with 32oz (2.2lb) of CO2 in it you would change your mind, and it's a lot of weight to carry remote in a pack? Getting liquid CO2 past the anti syphon is a real risk unless you run it half empty - which defeats the object of using a 1.1 in the first place.
I made the switch to air a few years ago after decades of using CO2, and wouldn't want to go back. Air is so much better for our climate - and most modern semi's wont run on CO2 anyway.
