I agree. The Megacycle cam specs looks the best to me too, but others are convinced that the Webcam profile is right.
It's all a matter of preference I guess.

MegaCycle - 126-20

lift      dur.   lobe ctr              Description                                                Timing
.363"   259°   104.5°      Must use modified piston and springs. Road           25 btc/54 abc .004"
.333"   259°   104.5°      race or street/strip. Great throttle response.         54 bbc/25 atc .005"

This spec is very close to the Yoshimura Cam of the 70's
