Limit orders for SPY

Now that $384 has been breached, I plan to start my entries in SPY next week with a more systemic and stress-free method. Do you like limit orders? If you do, how do you usually do that? Personally I prefer the catch-the-falling-knife (every 1% off) approach because I feel that I'm always involved/participated in the action.

Method 1: On every pre-market and provided the last close price is below $384, I'll set limit orders at 0.99x, 0.98x, 0.97x, 0.96x and 0.95x of last close price. QTY is 5 for every 5% off $384. So $384~$364.80=5 units per knife; $364.80~$345.60=10 units per knife, etc., etc.

Method 2: Set and Forget. I understand there's risk of sudden drop in pre-market and smashed through a few knives going down:
