I have a vortex shorty. Love it.
Comparison to M....hmmmm that's so subjective.
There's an idea based on the Pygmalion idea. A self-fulfilling prophecy concept. This in no way detracts from the e Vortex's performance. But after spending the dough, seeing it, holding it, etc. you're just like, "how could this NOT be amazing!?"
It's just that it rolls în the fingers so much easier than an M. It feels smoother and softer sonehow on your lips. The airhole feels so right. The amount of warmth on your fingers is perfect. The draw just feels so right. One's expectations are so high that how could this not possibly taste and just be everything better? Then, when cleaning, it's so easy, you're all, "yes, this is better".
So, each little thing is so incremental and tiny by itself it's not measureable. But, they add up to a better overall experience. It's hard to explain. Just... Simrell rocks. Get one.
