BE CAREFUL!!!!! Make cure the type of taper is the SAME!!
A lot of the Dufferin cues use what is called a "CONICAL' taper, especially on the Phantom and Sneaky-Pete models of DUFFERIN cues. This is the type of taper that a lot of the off the rack bar cues are tapered by. Now, Danny with JOSS uses a taper that is different than this, "CONICAL" taper, JOSS uses a Pro-Taper and has also used a "Euro-Pro" type taper as well, but they also can make any taper you want to customize your shaft taper to.
I just want to make sure you are comparing apples to apples. Make sure when you are looking at your old cue, that you measure the MM of the tip, then measure the taper at 4inches, 6 inches, 10 inches, 14 inches, 24 inches. Then if you give these to your cueman, then he can set-up the change in your new JOSS shape to have the same taper-turndown that you are use to. But, understand you will still need time to get use to the deflection and squirt exerted on the cueball and in the shaft. This will be different on almost every shaft.
Hope this helps a little, if you have any questions, feel free to give me a message and ask what you are thinking.
All the best, but like my father always taught me----MEASURE TWICE, THREE TIMES, EVEN FIVE TIMES, then cut once-----
Why?? Because the previous you can make a mistake and change the latter you usually cant fix as easily if you can fix it at all!!!
All the best and CONGRATULATIONS on your new equipment
HAPPY NEW YEAR
