Hello-
I've searched a bit and only found this thread, which is actually a lead closet arm.
I have a 4" cast iron closet arm. The flange was far over the surface of the floor, causing leaking issues on the toilet. I'm installing new flooring, underlayment and one layer of subflooring-- and want to use a modern flange that screws to the floor and I can easily adjust level of in the future.
I removed the flange (thanks to help from reading this form, thanks Terry for having it) and am trying to decide whether to use an internal vs external flange.
The internal flanges have a smaller ID, which somewhat worries me. I've been looking at these two Oatey products
Internal:

External:
http://www.oatey.com/products/drains-and-closet-flanges/closet-flanges/cast-iron-closet-flange
Any thoughts on benefits/drawbacks of External vs Internal?
My only thought is that the internal would allow for the floor to be closer to the pipe, insures wastewater enters the pipe without ever hitting the seal-- but would also have some restriction on the flange.
The external flange seems more robust and has no restriction, but the seal is on the outside of the pipe which somewhat worries me.
I guess the wax rings have a flange that directs wastewater into the pipe so it should theoretically never come in contact with an external flange...
Any thoughts/opinions appreciated.
Thanks!
