Well, a rooted cutting won't give you a dwarf. I know from experience that Meyers on Cuban Shaddock (Four Winds Growers and some others) do well. I don't have any experience with Flying Dragon; and the US897 could still be a gamble long term; it is a pretty new rootstock.

is Cuban shaddock considered a dwarf also?

In containers Cuban Shaddock has a dwarfing effect; it is generally advertised as semi-dwarf. I have heard that in field trials, planted in the ground, CS is or is almost a full size rootstock; but I have no first hand experience with that.

I also hear that in ground, when taken care of (like we do) it will become close to full size. It's not a bad rootstock, every single one has its down sides.

i hype up us897 due to great early results from trials, however as John said it has not passed the test of time. Flying dragon has.

Flying dragon, being in zone 5 your tree will spend more time indoors than outdoors.

I am not sure, but I think there may be compatibility issues of Flying Dragon with Meyer lemon..

Flying dragon is incompatible with Meyer lemon scions. It starts out great then the graft union breaks down and dies. Own roots should do very well and Cuban shaddock should stay small.

Poncirus trifoliata is the best rootstock for cold zones..

Thanks Guys, I have a Meyers from Four Winds that is doing great, Should I assume its on Cuban Shaddock?

I also have a new one from Harris which I don't know what the rootstock is, does anybody know what they use?

I Think I'm going to try my hand at a rooted cutting. just for the fun of it. at least if I fail a couple times rooting it wont cost me any money. anybody have any experience rooting there own tree?

Poncirus trifoliata is also incompatible for the Meyer lemon and will leave you with a dead tree down the road. Zone 5b you want a rootstock that can keep the tree growing a month longer in fall and start out in spring a month or 2 early. You are not talking cold hardiness because you are taking it in. Fruit dies when it goes below 28 so you have to bring the tree in anyway. Own roots in a pot with 5-1-1 mix as big as you can move when the tree reaches maximum size will give you lots of lemons and no rootstock suckers that get away from you

this site said PT Meyer good good

Do you feel lucky

Incompatibility can be worked around, use an inter stock.
