Going 50/50 on SPY/TLT won't help. SPY puts are expensive. Stop loss orders cause $$$ loss due to head-fakes and flash crashes that recover quickly. Selling covered calls doesn't bring much protection. What are some other ideas?
Can you give an example where it would be expensive?Index hedging is very expensive.

IMO any options price is fair due to the Put/Call parity, and you can very well use it for hedging, after all they are made especially for this scenario.
You don't need to keep it until maturity, just for the timeframe where you need the hedge, and then simply close the hedge.
If it is still somehow subjectively "expensive" then just use the "cheaper" Out-Of-The-Money strikes. Isn't it?
Put-call parity doesn't imply that the prices are fair in any sense, just that puts and calls are equally fairly (unfairly) priced. The market may still over or underestimate volatility of the underlying asset.
