New Kobelco SK210-10 jerky hydraulics

I have a new 2024- SK210-10 that is a little jerky when changing direction with all functions, swing and travel also. Its worst when multi-functioning for the spilt second when you change direction. I can only negate this by slowing down and feathering the joysticks. Swing is aggressive starting and stopping unless i feather-into the slew, it kind of thuds into slewing and stopping if you want to work at a decent rate. This gets draining over a 10 hr day and hampers productivity. Ive come from a smooth-as-silk Volvo 210 and admit im picky but i still think this machine needs some form of cushioning to the hydraulics. I dont believe the machine faulty as i found a couple of videos on youtube with guys highlighting this issue, they described it as 'Twitchy & 'Snatchy'. Seems Kobelco have gone for speed, power and responsiveness in this model and left smoothness under a stack of design drawings in a dark corner. I had a few ideas for mods with retrofitting a pilot accumulator a start. Seems odd it doesnt have one but maybe its not so effective in a positive control setup. A pressure compensated flow control valve could be placed in-line at the spool caps but this may slow down the function too much. As for the swing, possibly tweak the reliefs. What do you experts out there think?
