I like the stainless steel racking cane with the orange seal.
(Steril Siphon Starter)
What's unique with this cane is You can actually move it to the side of a carboy about 2/3rds down and see what you're doing. The red top is visible in even dark beers when it's on the glass.
There's no pumping movement to stir up trub. Simply blow into through the sanitary filter to start the siphon, or use c02.
I think the best added feature of this cane is you can vacate your secondary of all oxygen with a little trick. Fill your secondary with starsan, then remove the sanitizer using the cane and c02. Then cover in foil or plug, you then have a secondary full of c02, and not air. Some caution though, carboys should not be put under pressure so your c02 pressure and flow should only be enough to fill the void under normal siphon gravity flow. Though I have transfered from carboy to carboy with no elevation change with just a couple psi with no failures.
Minimize your trub (a bit off topic but worth mentioning)
Use your whirlfloc or Irish moss properly. Many times too much is used, and it is used wrong making a huge amount of fluffy trub. 1/2 a whirlfloc is the recomended amount for 5 gallons. A whirlfloc is really only effective IF you whirl pool and leave the hot break it collects behind, it shouldn't be racked to the fermentor. I've discontinued the use of them and still make brilliantly clear beer with normal post fermentation finings.
Use hop bags in the boil
This is the single most thing that will reduce your trub. I like my hops to float free and bagless, so I use a large BIAB bag so the hops don't feel trapped and can float free.
Use Hop shots this is a great way to get generic bittering with no plant material to add to the trub.
