I know this is not the place - but I would think twice about the Regulus. I had one. It is the only yoyo I have ever sent back to the vendor.
Because the stock response is too thick for the response seat - the yoyo is almost impossible to throw straight. Somewhere on the breakaway - your string will catch on the protruding response and cause a tilt or wobble. If that does not get you - the placement of the steel rings on the very edge of the rims means that this yoyo precesses (rotates about the string) more than any other I have used. Other than that - I will say that it is a good-looking yoyo if you are into that sort of thing.
If you want to spend your money wisely - save $10 more and get a CLYW Chief.
