Gyroscopic Investing

What are peoples' thoughts on the merits of VGSH vs SHY? I generally trust Vanguard more than BlackRock.

IMO: neither is perfect but they are both acceptable. SHY tracks a Treasury-only index, is older and better established, and has a higher volume. VGSH is sponsored by a (subjectively) more stable and forthright organisation and its expense ratio is one basis point less. BlackRock's asset lending practices are a little scary. VGSH includes a handful of mortgage agency bonds which are a little scary.

I prefer SCHO. It basically gives you what SHY does and adds institutional diversification if you are also using TLT.
