Not wanting to argue with you, as pulling logs high with the 3pt whether boom pole or not, there is an inherent danger of the front end lifting up and coming back over. But realistically it is not in a split second (I interpret that as less than a second). Simply not true.
If pulling slow and steady (hard to do anything esle in the woods anyway) and the log catches, the front end will lift only as fast as the tractor is moving forward. If either of two things are done, it will stop. Either lower the 3pt, or stop moving forward. Both are reactions for which you have plenty of time, I have found since doing pulling this way for over 40 years with 3pt tractors.
Attached is how I do it now, and the FEL on the front helps to add weight. On my first 8N Ford, there was no weight on the front unless one or two guys would ride there. /forums/images/graemlins/smirk.gif
I often use the tongs to grab the log in the woods, then lift it, and throw a chain around it so the log won't slip out on the drag out to the log deck.
