the classic rose stem is obviously the most popular but I find them to be vastly inferior to using a radio antenna. They conduct heat way more efficiently, they pipe has a smaller circumference so it vapes it quickly and with very little direct contact of the flame and best part you don't have to rely on chore as much because of the smaller circumference of the pipe, its not as essential to get it to melt all into the chore and will vape just as good off the sides of the pipe since it heats up so fast and the best part no hairline cracks happen like with the glass.
