My preference is the cut-down 901 tip. Looks great and works great. I haven't had problems with juice in my mouth, because they are cut pretty short, right up to where the D-shaped hole starts. I also use 801 soft rubber tips from time to time, they tightly fit over the carto and work well. The only problem is that after a week or so (admittedly switching it out between many carts) it stretches out and fits more loosely, but they are cheap. Also, you can get the 801/901 T tips and use those. They are a little more pricey, but they last forever and come in short or long, brass, stainless steel, or aluminum. I almost ordered one, but another supplier has just introduced derlin dripping tips that again work on cartos. I think I'll give these a shot as they are much cheaper. PM me if you want details, I'll be happy to help!
