I loop to loop my floro tippet to the leader - even for flats.
I never use anything less than 14lb floro for striper tippet. I usually go with 16# or greater.
The new Gen2 floro is so small in diameter that there's no reason to go lighter IMHO. Not sure what the actual percentage is, but loop to loop is up there for breaking strength compared to blood knots/surgeons.
One last thing to consider is what kind of mono you are using to construct the leader - they are not all the same. I use RIO hard mono (3ft 35#, 3ft 25#) and it wil turn over just about anything (credit to Jim Bender for the "formula")
