Indicator Design Question. Buffers vs Objects

 

Hi all.

I would like to make a question about the optimal design and performance of an indicator.
Let's say we want to design a complex indicator which it is required to draw many arrows and lines, for example the total amount is 30. 
Is it a good practice to create all theses different symbols with buffers or with objects ? I know from first hand that if you have many objects on
the chart then things get a little slow but if i have many buffers maybe is worse ? 

Thanks in advance!
