Here's a picture of the only people who don't make mistakes.

twtaylor and I should get together and compare notes, I'll bet together we could really screw something up

When I first read this, I thought you had to remove the horns to cover the plane. As far as trying to remove the horns just so you can in case you ever have to... With all due respect - What are you, NUTS?

I can't think of a single time I ever had to replace a control horn. If those things are stuck - GOOD! Just leave them like that.

If you ever have to replace them, THAT's when you should worry about it. And there's a 99.5% chance you'll never have to go there.

Also, what kind of plane is it? Where is the rudder servo located? If the servo is not in the tail, switching to a pull-pull isn't going to save that much tail weight, and unless it's a 3-d plane, you don't even have to worry about it.

Add some lead to the nose, it's really not a crime. We do it all the time.
