I got the Thor black and love it, a few things to note, the Shaft is thick i have not measured it but it feel like at least 13MM that size shaft is perfect for me, all my shafts are that size.
The only thing i could think of is that thickness is maybe because it was part of the design, maybe sanding it down will take away from performance ? i don't know
I have not even shaped the tip just a little scuff so the chalk can grab. I got the 18 once one, i always favored the lighter break cues.
I had the BK2 years ago and if i had to pick one it would be the Thor.
Now Milage will vary from person to person, but with the way my break mechanics are the Thor worked out Awesome for me.
Not bad talking the BK2, the shaft was just to thin for my liking.
