Aye, I like the speed thread provision, ye faster and the threads don,t pick up as mush debris in the conventional iso threads. However, there was a concern raised regarding the speed thread in that, they were apt to slacken when subjected to vibration---this concern has never been proved and may be an urban myth---however, if any of the Scaffs has any information to the contrary please let me know---I carry a quantity of Mill'iz 90z and P/Cz for task specific jobs and cant see past them.
