I know this has been asked and answered many times before im sure, but what is the difference between all the threads, and why do some brands, such as pechauer and Mezz use theyre own style, which makes it difficult to swap shafts if the occasion ever needed it. I have used all threads, from uniloc ( which is garbage IMHO) to 3/8 11. I like the bigger threads better, but i also like the 5/16X14 and X18, it all depends on the cue maker or brand, but is this all in my head, or does wood make a difference or what??
