I've been using 8# Trilene MAXX mono with good results so far. No break offs, sensative, good knot strength. etc. No complants here.
Why are you thinking of going to 10#?
I don't spool my whole line with Seagur b/c that sh@#t is expensive. I use P-line Flourocarbon coated as my main line, then tie it to a swivel (to eliminate line twist) then apx 25" of Seagur as leader.
Reason for the upgrade is b/c I dropshot right into thick patches of weed sometimes and need to haul fish out fast, also 10# would be more abrasion resistant from their tiny toothy mouths.
6 was too small and only worked in clear open water, 8 has been working fine, haven't lost a fish or setup yet but I'm one of those who is never content, always wondering if there's something better out there.
