Legit to use Fraps as a 3rd party program?

Is it legit to use Fraps as 3rd party program to defy Crossfire's ladder movement speed?

Another words, if you have high FPS, around 200 going up/down a ladder takes ages and puts you in a vulnerable position.

Solution: Set Fraps to record at 40fps (you want low enough fps to fly up that ladder but also high enough to still be playable for those few seconds). For easy and fast access set ` ('console' key in most games) as the Start/Stop Record key. When you approach a ladder start recording, speed hack up that ladder and then stop recording.
