Well here's one

I had my Carbon bike rims drilled out at another shop, it cost about the same (and + the cost of two new tubes). Money well spend.
As for the adapter, no they don't work either. If you inadvertently screw them on at an angle of 89.99° instead of 90.00° they get permanently stuck and you have to replace the tube anyhow and again I wouldn't trust them with a flat. Schrader valves air or the fix a flat goes in the 1st time everytime, while with !@&* Presta valves even with an adapter it can often take several tries before air actually goes into the tube, with fix a flat you have one can and don't have several tries. Sure I could carry more cans but then there goes the weight advantage with aluminum rims.
