Replying to Adding grabs to spins

Got my 3s and switch 3s down pretty nice, bringing the knees up, controlled and even spin, basically picture Henriks yknow? (Obv not)

Everything changes when I go for a grab. I'm trying to wait until 180 to grab so I get a good pop and commit to the rotation, but I still have a tendency to pause my spin when I grab.

Part of me thinks it's because the jump is too small so I don't have time to do a slow enough rotation to lock the grab, but also could just be my technique causing problems. I'm hitting the medium ones at Brighton but will be working on brining my 3s to the large jumps here soon.

What helped you in this situation or what do you think of when grabbing during spins?
