I just got my Riva 901 kit in Friday from Liberty Flights. I had ordered a drip tip with it, which I started using right away. But I had also ordered some extra, blank whistle-tip carts. With the drip tip, I was only putting 3-4 drips in because it would start to gurgle with more and, frankly, I was pretty much constantly dripping.
So, I decided to go ahead and give the carts a shot, leery because of getting the fluid in my mouth and inconsistent flavor/throat hits using my old 510s and 4081s with carts. BUT as it turns out, you can get 7-8 drops into these carts, they do not leak, the flavor and throat hit remain smooth and consistent as does the volume of vapor for the equivalent of about 3 cigs.
I'll write a more in-depth review of my stuff later but just wanted to get this out there; I advise getting the whistle tip carts (I suspect the round ones work just as well as LF sells quality items... these blank carts, for example, had three layers of packaging/protection for each cart; these tips are great with your Riva 901 kit so you don't have to constantly drip.
