I must be pretty lucky and I’m no expert.
My Blade depower mod took me under two hours to make and install and probably cost 20 bucks tops.
Tuning it definitely involves some launching and landing which is so much more efficient if you have a friend to help.
And I’ve probably had 60-70 sessions so far this year alone on my 16 year old depower 10.5 and 6.6 Blade III.
I love the way they launch, land, turn, depower and pack down for travel. And they last a long time.
But I understand why very few people would like them.
