Re: Which is a better mya??
i would go with looks between the 2, they are so close in size. i would also look to the mya mini (acrylic or glass), the acrylic can be had on ebay for like 16 bucks + shipping (which was a total of 25.60 out of my pocket, half price of one from a vendor after their shipping).
its a taller rig but still very portable and smokes very well, just with the smaller rig i noticed you can feel the bubbles more in the pull than some larger vases but you get used to it pretty fast.
over all myas will be great smokes and their small rigs are awesome
