Quick question about filling up a spool. I only have enough line leftover on a spool to fill up a new reel 2/3 of the way. Could I take the remainder of line needed off of a different reel that it was replacing if both lines were the exact same type and lb test, and join them with an Alberto knot? I usually use that knot for joining braid to a different diameter leader so I wasn't sure if joining different diameters was some unique quality of the line. If some other knot would work better for joining identical lines, then I'm all ears. 

I see no reason why it would not work.  When the knot is buried quite a ways I use the double uni because I have had trouble with the alberto in the past, but I've solved my alberto problems and like that it's much smaller than the double uni.  I don't think that line diameter is relevant to the alberto like it is to some knots.

That is how I do it.  I also put tape over the knot so I can see when I am getting close to the splice.

put the other line on first as backing. then put the 2/3 spool on.

Yep. This will save you a lot of line in the future. Use old line as backing and put the new line on top.

Also when replacing line, I only strip off the section I have used. I put the new line on top of my old line. No need to take off what you never use.
