Lots of line preferences.

I have good luck with Sufix Elite. It is mono...all mono will have some memory. I use it predominantly on 30 size spinning reels...but also on smaller spools. One thing I believe works is spooling the line then go in the backyard, pull all the line, attach nothing to the end of the line, then use something like a wet rag to apply slight pressure while reeling the line back in. This helps with removing twists that can present casting challenges.

I realize you asked about 'no memory'. Hope this is helpful info, and good luck.
