What type of Tips would you buy

I'm not Jim, so take it for what it's worth, but for me Tbills are for preservation of capital rather than return on capital. I am hoping to redeploy the "cash" into Berkshire and/or the rest of the market when it has retrenched sufficiently. Brk.b at $405? Sure would be nice to not be locked into a 2-year Tbill or Tips when that blessed day happens. So for me 1-month Tbills make sense. They respond quickly to whichever direction the Fed takes interest rates. If you aren't worried about getting back into the market and are preserving this wealth for your descendents then perhaps tips make more sense as they also have some inflation protection and you can stop worrying about the market. Really depends on what your investing goals are.
