How interesting. Rhino just released a new line of cues called Must. How surprising.

These ones are described as having a carbon fiber butt instead of carbon composite.
I am having a really fun time with their customer service department trying to get a replacement Must shaft in exchange for the wobbly one I received. Hell, David Schmelke had me a return label within minutes if the cue I received from them was flawed in any way. Rhino runs you through the gauntlet and no amount of evidence seems to be enough to accept they sent a shaft that is out of spec.
I am not going to lie, I am biased when it comes to where things are manufactured and I prefer US cuemakers. I like Predator cues, and although I do not like that they are made in China, there is no question that they are top notch. Same with J. Flowers, Cuetec and a few other brands. Just a personal preference. I chose Rhino because they manufacture their products in Vietnam, the price was right and I thought "what the heck. Lets give them a try, not much money involved". But, at this point, I think I will take my business elsewhere for a mid priced carbon fiber shaft backup cue. I really, really like my Rhino Eclipse II cue with their standard shaft and play with it often, but it will be the last I purchase from them.
Have heard nice things about Raven out of CA. Made in China, but they stand behind their products and their prices are attractive. That is worth something to me.
