The Titans are OK for lightly loaded lines, but while I have never broken one the amount of twist they develop when heavily loaded is off-putting.
And as for the floating bit, it just distracts the helmsman while he decides not to turn around!
Used the Titan handles on a boat they sponsored, things did work but were far from comforting to use when they would bend/twist, enough that the handle was at about 20 degrees to the vertical, and that was just the single handles, the doubles!
