Citrus General Discussion / Re: Vigorous and productive seedling citrus rootstocks?

I have only just started using C-35 and most of my comments are based on reading studies. So far C-35 does appear more vigorous than trifoliate. I believe it tends to stay smaller than others due to earlier larger fruit sets, thus always behind in tree size, not because it is slow growing. If you are concerned about tree size, Carrizo is a good option as it is 10-20% larger than C-35. You must also consider that some of the vigorous fast growing rootstocks can produce poor quality fruit. Eureka Lemon and Fukumoto Navel do appear incompatible with C-35 and Carrizo.
This is a good overview of rootstocks:

If this is for general backyard use I would seriously think about the size the trees will eventually become. Large trees use a lot of water and fertilizer and will produce a ton of fruit that could go to waste. Most trees on anything but Flying Dragon will still reach large size for backyard use. If the trees grow large and start crowding each other you will have to prune which will cut yields because citrus flowers on new growth. The reason I suggested C-35 is that it produces one of the highest yields per area for citrus rootstocks. ie. the yield is the same as Carrizo but on a smaller tree.
