I tried it last week end in 15 to 20 knots on a TT board and 23 m lines. Not light wind... . 20 knots is its sweetspot for my taste on a TT board.
At launching, you need to tension rear lines kranckly to complete its filling of air, similar to f-one Halo.
Liked it a lot as well on a TT. a lot of power with boost... Still really stable, upwind is good ! Jumps have not as much hang time as Elf jocker 5 or sonic2, but better or "easier" than halo I have found.
My jump heights were irregular. Sometimes high for my level, sometimes low. Maybe 23m is too long to get tolerance on timing, or at least i need to improve my understanding of its timing . When timing was right, height was excellent (better than FRS), maybe a bit lower than Halo , and hang time and smooth landing was easier than with the Halo. I need to tune my timing to be more sure of spirit's jump abilities. One or 2 jumps were very high for my level. I think that more depower would have helped to prepare my jump with those quite long lines.
Bar pressure is medium, between the lower pressure of f-one halo and higher pressure of Koala. The Sky Country agent says that it has a bit less bar pressure than Soul but I do not know the Soul in those medium winds. Approx similar to FR:S and pulsion overall.
Depower is efficient and instantaneous. Between the excellent depower of FRs and the more limited depower of the Pulsion. Far better than the "old" pansh A15.
It turns well, long or short loop, with less latence than Pulsion (which is great but need 1 second anticipation) , similar to the excellent halo and FRs, except at the second half of the loop which get a larger radius if lines have lower tension. I sometimes needed to pull the bar more in this second part if I need a complete short loop. however loop with slack line is 1000 times better than Pansh A15 and better than Pulsion "S".
Very good stability , less wing tip folding and backstall than the Halo, almost similar as the incredible stable pulsion.
I think that high end is similar to Halo, so in-between the very high end of FRs and the limited high end of Pulsion.
Really happy and very "living" kite.
