[TPIN] 13A4A question

[Stuart Swain]

Quoting JFDonaldsn at aol.com:
> It isn't just you. There is quite a difference. According to Gerald Endsley's
> Comparative Mouthpiece Guide the depth of the 13A4a is .387 inch and the
> depth of the 14A4a is .428, a difference of .041. This is considerable given

And just a reminder too about the Kanstul mouthpiece comparator, found at:
http://www.kanstul.net/mpcJN/Compare/CompareFF.html

Illustrates the above point quite well.


Cheers,
