Experience with New F-One Tails? 138 vs 141?

Would love to hear insights from anyone that has tried the new F-One stabilizers. In particular, I’m curious to hear how the new 138 compares to the 141w. I’ve heard that the 141 doesn’t pump very well, but I’m not sure how much difference the 138 would have in that respect.

My use case is mostly wing wave riding in the Gorge on a Sk8 850 and Eagle 790. I want something that’s faster than my 160 carve stab, but still pumps OK for connecting sections.

Thanks!
