The other thing about the 190 is that it does not go all that high without raising the centre column which makes it more unstable so if you don't want a crick in your neck when shooting wildlife the 055 is better, the downside is of course it's heavier. I have been thinking about getting a carbon fibre 055 for ages but the money is the problem and of course persuading the wife I need another tripod when I already have a ''perfectly good one already that you have had for 30 years and you never use anyway''
