I've been on the Takuma Kujira 980 and 1210 for around 8 months. I got to demo the Lift 120, 28" standard mast with 34 glide a few weeks ago, I liked it and bought the setup. I only prone foil.
I'm 5'7" and weigh 140 lb (63.5kg). I had heard that the 120 was tricky to ride, but it seemed just as intuitive as the Kujiras.
The 120 turns just as well as the 980 and for my light weight, it seems to pump just as well as the 1210! The 120 also feels like it has more gradual lift on takeoff, so taking off on HH waves have been easier on the 120 compared to the 980.
The K980 and Lift 120 seem to have very similar turning radius, but I prefer the Lift 120 for turns because I'm more likely to breach on a hard cutback with the K980.
For pumping out the back, my longest pump on the K980 has been 80yd (73m). With both the Lift 120 and K1210, my longest pumps out the back were 120 yd (110m). I seem to be tapping out due to lack of cardio on my pumps out the back. For me, stall speed for both the Lift 120 and K1210 is just below 7.8 mph (12.5 kph). Stall speed for the K980 is slightly higher.
Before, when the surf was below CH, I would ride the 1210 because it was easier to pump and more reliable for getting double dips. Once surf was CH+, I would switch to the 980 because the 1210 had too much lift on takeoff and I would end up getting launched. Now the Lift 120 covers all the conditions I want to foil and I'm not questioning myself if I pulled out the best wing for the conditions.
I ride an ONO Dish 4'4", 36L board. With either Kujira, I had the mast all the way in the back of the tracks with dual baseplate shims; no tail shims. With the Kujiras, when I tried moving the mast forward to improve pumping, I was more likely to breach during a cutback.
On the same board, with the Lift 120, the mast is 1" (2.5 cm) from the front of the tracks (no shims).
So far, the only negative for the Lift 120 is that the wing hums. Neither Kujira wing hums. I might have to do some sanding on the Lift to get rid of the humming. I don't want to attract any sharks with the humming.
Here's a video of me riding the Lift 120. At the end, I felt like I was about to stall and put too much back foot pressure and breached; I should've been able to keep going.
