With the trigger I bring in the additional Fields (I think say 6 of them) that I require, where as the ‘Read’ node brings back all of them, almost data overload, as theres 25+ columns, and this additional data unforntately doesn’t appear to help the additional steps in the flow. 
What you mention about the trigger is also a concern of mine and something I’ve questioned the Founder about in Reduce workflow iterations - batch? - #4 by harshil1712
