I have flown the 10m Turbo Diesel in high and marginal winds. For me, I would put a comfortable range for the 10 TD at 14 to 30 or so (not 40).
Donna now has a 10 and a 14 TD. She stops riding basically at 25, so this is a two kite quiver for her.

They (TDs) seem gruntier to me than the Waroos.
Not that that is good or bad.. it just is.
They also seem more stable and alot less twitchy (in terms of shooting to edge of window/ fluttering) in gusty winds. I would not put Donna on a Waroo with its current setup. I just don't trust it yet. That's just as much a "feeling" as anything else. Can't put it into words or being scientific about it... it just seems a little unpredictable to me.

On a similar note. I am honestly clueless on this one.
What DO you do to save yourself on a bow? in a bad situation?
Rely on it dying by use of front lines or hook it up to a back "oh shit" setup? or just let it GO for good and pray it comes back?
I have ZERO experience with these things whacking my a$$, so this is a serious question.

Also, how do you self land them?
