Windind Shape??

hey guys i just got a new reel and it came with washers to adjust line lay. My question is for casting light plastics and HB's with 6lb sunline super PE should i have the line lay.

normal

more to the front of the spool

or more to the back of the back of teh spool.

my reel is a stradic FI 1000 and it has a angled spool lip which sticks out further so i thought having more to the front will fill it better and therefore it should cast better.

any opinions??
