Plug, I can understand what you're saying, but I've never experienced the problem you're describing. Although most of the downward line pressure is at the tip eye and the pressure on the reel is horizontal (more or less) and there is little downward force on the reel.
I've regularly used 7000s, squidders, etc. on 10 footers and never experienced this. I also use 113Hs (which is a relatively wide spool without a levelwind) on my 6 foot boat rods and have not noticed it. I've used 49s and haven't noticed it (but that is a very narrow spool).
I'll just have to trust you on this one
