Thanks for the help everyone 

Bob Dzuricky actually posted an updated picture for that one because he said it wasn't really a fair comparison between the two pins--something about the wood used didn't show how well the threads on the 3/8x10 (not modified) normally fit the v-cuts for threads. Here's the new updated picture:This picture tells it all. And I think it shows the advantages of a modified pin. But I am not a cue builder.

Regarding questions about the backwards compatibility - when I used the std 3/8-10 pin, I bored my shafts to .302" diameter before running a tap into it. This was a smaller hole than most used. I liked it because the pin had a tighter fit. Again, there's that intimacy I like. The problem arises because the modified pin has a .308" minor diameter & will not fit into an older shaft unless the .302" diameter is enlarged to .308". It takes about 2 minutes to set it up & run a reamer into the existing hole.
