I'm not ringing in personally as i have no idea, just tryin to get as much info as possible, unfortunately some of it's contradictory...

The LN tool is a knock off of the OEM tool, but of the
cam locking tool, not the
cam holding tool; they are two different items with different part numbers.
Your indy is correct in that spring pressures are reduced at TDC, but they are still there or you would not need the locking tool to keep the cams from moving while doing an IMS witht the engine at TDC. The cam locking tool keeps the cams from turning under spring pressure, the cam holding tool keeps the cam in the journal saddles after the cam cover is removed, other wise one end of the cam would simply pop up from spring pressures, possibly breaking the cam itself.
At the end of the day, it is your car, and you can do it any way you please........
