Shaping your tip to Dime(9.1) or Nickel(10.5) radius.
What is better for accuracy, deflection and not miscuing?

A dime is more accurate in the sense that the contact area is closer to the center-axis of the shaft. For a given offset of this axis, dime will produce more squirt (deflection) since it produces more spin. I don't think that either shape has an advantage with regard to miscuing.

As a 50+ year old returning to the game after a 30 year absence, I've been tinkering with tip radius in search of any kind of advantage to offset my declining eyesight. Take it as one man's opinion, not scientific fact. I've made shapers with 120 grit wet-or-dry sandpaper glued to different sizes of plastic pipe or tube. My results indicate a smaller radius is best for pinpoint accuracy in short, sharp cut shots with heavy English (which is probably why it's the snooker player's favorite), but larger radius gives a little more forgiveness with hard hits or longer shots. My current favorite is 1 in. ID tube less .040 sandpaper, which is close to a .950 Quarter shape. Any larger moves the contact point out too far on the tip when you're using heavy english. You might want to try some different sizes for youself, and give them all a test at the table. Email me for shaper constuction details if you wish. Hope this helps.

Normally, I will start with a dime radius, and after playing a while, your tip will take the radius that suits how YOU play.

FYI, my July '06 instructional article (http://www.engr.colostate.edu/~dga/pool/bd_articles/2006/july06.pdf) discusses and illustrates the effects of tip shape and its relation to miscues. You might find the article interesting and useful.

The link works fine for me. You can try instead going to the articles section of my website (http://www.engr.colostate.edu/~dga/pool/bd_articles/) and clicking on the July '06 article. If that doesn't work, I don't know what to suggest (except try a different computer operator /ccboard/images/graemlins/confused.gif).

I shoot with a Moori hard tip and use a dime radius done with the ultumate tip tool! /ccboard/images/graemlins/grin.gif
