So, for 2H weapons, the traditional standard has been .606 cores (the PVC plus aluminum combo predates even that, but is generally disregarded due to the huge weight). However, as the years have gone on, the manufacturers have gradually reducing the content of fiber in favor of a lighter binding agent. This makes them lighter, but much less stiff. To compensate, some of us have scaled up to the next size for cores, which is 0.75. They don't whip as much (though they still do) but require a bigger size of foam as well. The other thing I have been playing with is 0.5 carbon fiber core from Dragonplate. It's only about 30% lighter, but it most importantly doesn't whip as far as I have seen. It's more expensive and runs the risk of snapping, but under the typical strains I put them under it seems to have been fine. My 2h sword is the first I made and it's still intact after a year and a half of use. Also, a neat extra benefit comes from the fact that the "blade" makes up the bulk of most boffer weapons, so the lighter overall core pulls wight back from the from the front of the weapon, improving the balance and heft.
As for knobs, the thing I tried was buying some open cell foam from a craft store and carving it into a sphere. Then you can glue/tape it onto the top of a weapon.
