RooR downstem help me measure before ordering

I broke my original roor downstem and bowl. I'm looking to upgrade to a RooR diffuser downstem and don't which size to order. Here is a pic of my downstem measured in at 6.5 inches which converts to 16.8cm and looks really close to bottoming out at 16.8mm. I have two choices for replacement downstem in 15.5cm that will work but will requires more water in the bong to work or 17cm and risk the downstem not fitting right as it "looks" like it is going to bottom out with the original roor downstem measured at 16.8mm.

I'd go 17cm, I think the risk of it sticking out another .2cm wont throw off the look really what so ever, just my thoughts

Hey dudes I want to buy a cigarette rolling machine and I discovered this one named Duke cigarette rolling machine. Anyone utilized it and can give some feedback? Premium tobacco is way better than regular one? Rolling is a messy job?. I am a beginner in this "domain" so whatever feedback you can provide would be appreciated. Thank you

My advice, don't get a rolling machine. The filters will filter out pretty much all the THC if you use em, and rolling by hand is far more satisfying.

I'd get the 17, its only .2mm I doubt it'll bottom out.

.2mm aint shit

2mm is something.
