Re: im stuck between two Khalil Mamoons
They both look fantastic and smoke great, like all KMs. In the end, making a decision comes down to convenience: how tall is "too tall" for you? In terms of moving around and cleaning up, you might find a 40"+ hookah to be very inconvenient. Measure it up and choose accordingly.
Like Bradedup said, the trimetal is more of a solid product, but if you don't tip over/beat up your KM, you shouldn't have a problem with construction either way.
But, more importantly, enjoy it!
