Regaining &inproving top speed

Topcat, think Lane4 means 3.6 for 30m not flying 30m.

Yes, i have found that flying 30s do fatigue me more than flying 20s.

Just thinking, when doing hurdles hops, would it be best to keep the hurdles low and look for fast reaction off the ground. almost ankle popping over the hurdles, if you know what i mean? These may help develop top speed more due to hip & knee angles & ground response, where hopping higher hurdles requires longer ground contact times and deeper hip/knee angles to gain the power to get over the hurdle, this may help acceleration more than top speed??.
I know lance brauman used to get his Arkansas athletes to jump hurdles, land in a half squat positions, pause then jump the next hurdle, for 5 hurdles,then into normal hurdle jumps for 5 hurdles.

Charlie, what kind of hurdle height, hip & knee angle would you be looking for?
Thoughts everyone?
