I don't know if you guys who build this light stuff run into this, but the main triangle tubes aren't the parts that weigh me down, its stays and forks. There are a lot of issues, but among them is that these parts are swaged (or whatever they call the tapering action). There ends up with a lot of beef in the bits, A fair amount of this could be reamed out, I don't think it's in there for any reason other than it accumulates during the process. If it was up to me on an all things equal basis I would prefer to remove metal from the ends than the middle anyway. My point being if you need to steal back 114g there would be a lot of targets in a bike, other than the main tubes. But maybe the stays on your race stuff are already processed. I don't bother on most touring size stuff.
