Of course it depends.

However the question appears to be about a standard pneumatic ram ( double acting ) mechanically attached to the bot base and flipper arm... rather than a single acting F.P. ram with the flipper arm free to move and restrained/damped by bungee cord.

Hence ..
Cushioning is .. IMO .. a good idea.
IF Max has access to machining facilities and feels competent it may pay him to remove the return / base cushioning and thus shorten the ram.
