The huey manual says to not touch down with more than 25 knots due to the risk of ripping off the skid gear.
You're talking to an old timer here, just checked my Huey manual and there is no limitation listed for touch down speed, perhaps your limit is a later addition. In any event, if having to use the 35 knot procedure in the real world being able to walk away, or at least still alive, would be the only measure of success.
