New Downstem - What one is right?

Hello RIU peps,

I'm going to be purchasing a new downstem soon and I ran into a bit of confusion while doing research over the web about my choices.

I have a 12in straight tube, with a four-arm tree perc, and a 4-arm ws ashcatcher. I might be replacing the ashcatcher with either an inline, one with more arms, or a showerhead.

So when I was doing my research I found out it matters what downstem you get depending on how you position your bong as you hit it, and if you have a beaker or straight tube ect.

My problem is I don't know which one would work best for me if I got a tube straight bong but tilt it back.

My choices are between the SG 180degree gridded, LG 6-arm, or an Alex K showerhead.

Hope to hear somethin good,
Ben

In this order:

SGW showerhead

SG 180* gridded (very close 2nd)

Roor .de diffuser

Alex K. showerhead

Luke Wilson six-shooter (problem with these are the non-reinforced arms, though he may have changed that by now)


You're welcome.
