What monofilament line do you use?

[45user]

i have not read much discussion on fishing lines here. I spool most of my reels with braid and short top shot of flourocarbon and mono. I was wondering What monofilament/flouro do you use? I just use whatever I have at the time, mostly izor xxx or p line (and Seaguar flouro) I was told p line is less stretch than the izor xxx
What mono line has least stretch in your experience?
Thanks for sharing!
