I'm feeling the same way really. I plan to read all the rules as they are, and heck, just like I did way back when, I may actually play them as is (or at least try and see why folks change them in play). I'm not the tweak-master in general (unless something is just plain stupid, but that's rare). The only thing I remember really houseruling when we played was the experience counting business, but I haven't even had a chance to read the thing yet - just a flip-through last night.
I'm even using the experience counting business. Learning new skills in CT is rare (learning by yourself is in LBB3, quicker learning with an instructor is in LBB4), but if a character is at his experience limit, I'll have him "neglect" a more unused skill to make room for the new one.
I like what MWM said in LBB3. That what characters know, their skills, are fluid. Thus, if you're a sniper, you'll be at the peak of your skills (highest rating) when you're practicing a lot (during the time you're a sniper in the military, for example). Years later, you'll probably still be a good shot, but maybe not as good as when you were at the peak of your game. Thus, your skill level may degrade a bit some years later.
That makes a lot of sense to me.
I can still ride a bicycle, I'm sure, even though I haven't been on one in years. But, I know I can't do the things I used to do on a bike when I was 14.
Now...if I practiced, I'd probably get my skill level back up.
Thus, skills really aren't that stagnant. They tend to vary, up and down, a point or so, as we let our expertise slag.
I'm sure if I didn't type for a while, my typing speed would decline until I started practicing again.
The experience limit is a bit of a "game mechanic", and I know there are arguments against it. But, I think it works. (And, I understand the need from a mechanical perspective too.)
