I have 4 Becue shafts (all 12mm Prime M, 2 - 5/16-14 and 2 Becue B-Loc joint) and 1 of their cues (Blue Prestige).
I have been playing with their shafts for 4 years and their cue for 2 years... I now only play with their Prestige cue.
They hit really good! Solid with NO ting sound. I have played for 50 years and still can string 6-8 9 ball racks and
run 100+ in straight pool... these are the best hitting cues I have ever played with... IMHO.
The new Engage hit a little stiffer. The Prime M have a little softer hit. I don't use their playing tips though I play with G2 med.
