I didn't say SMJY wasn't perfect; what I said is there is no way all 3 are, and i believe i'm correct.
shows an obvious difference in height between auth and sxk. i love infinite, but it seems obvious that in this instance, it is not 1:1, therefore is either inferior, or at least not what i'm looking for.
so it seems (unless that has since been corrected) we are down to sjmy and tobeco. smjy seems alright, but again i want to make an informed decision; not a guess.
All the info you need is right here in this thread. If you would read it, as I did, you would see that the SJMY comes out on top.
I believe there's only one person that had some problems with his or hers, at least in this thread, and if I recall correctly that was o-ring related.
Most people seem very happy with there Tobeco as well but from what I gather it is agreed upon that the SJMY is the nicest with the smoothest threads by people who have both.
