I went to Academy to restock on some Invizx and Power Pro braid, but also noticed that they had Tatsu on sale so I got a little spool of 10lb as well as some 20lb Super 8 Slick V2 Power Pro. Never tried either line but am going to take the kayak out on Ray Roberts tomorrow to test them out. How does Tatsu compare to Invizx?

In my opinion, it's about equally manageable and a solid step up in every other way.

I think Invizx is softer, more mono like, and last about 1 season for me.  Tatsu on the other hand is stiffer but more durable and more sensitive.  I've had Tatsu last me about 4 seasons. 

This isn't entirely true, but it is close: Invisx has a bit of stretch to me, great treble hook line. Tatsu is more of a bottom contact line, less stretch. 

 

Also if I recall correctly, Tatsu has the same coating they put on their leader lines and is (per Seaguar) suitable for a leader. Better heavy cover line too.

 

If you took away my tatsu and said you can only use invisx, the only thing I'd really be bummed about was bottom fishing and long-cast single hook applications like an owner beast. 

 

In both cases, amazon is nearly unbeatable for pricing.
