Condenser coil question

[midwest shinner]

I am just wondering what most people use to make their condenser coils? I know the common size copper used is 1/4" but there is a huge difference between 1/4" copper pipe and 1/4" copper refridgerator coil. This condenser will be going in my 2" vm/lm , I bought a roll of 1/4" refridgerator coil a while back but got to thinking when getting the rest of the parts for my build. Is the refridgerator coil going to have sufficient coolant flow for my reflux column? I'm sure some others have experience with this issue as well, so just looking for some feedback. Any help is much appreciated, thanks

Midwest,
I used refrigerator 1/4" just because it was handy. I ended up with an 8 inch long, single coil, that will knock down anything my 2 inch column can put up. This is partly because my submersible pump can push enough condenser water through it, that it can keep any and all vapor from exiting the column. I added one small, cheap, water hose, Y- valve for adjustment, and it works fantastic. The best part is, it was cheap.

Do you use the y valve to send water to both your reflux condenser and product condenser? Or 1 hose to the condenser and the other back to the cooling tank?

One side of the Y-valve goes to the reflux condenser and the other to the Graham condenser. The Graham side is always wide open, But the reflux side I have to fiddle with as the run progresses. I have both individual condenser outputs meeting in to one, 1" PVC return tube, back to a 55 gallon water barrel.
