Best way to remove screwed PT deck boards

I'm killing myself here. I can unscrew some, but most of the screws cam out. Used pry bars, wrecking bars, sawing... any secrets to take these old boards off?

I think I'd try drilling the head and then use the wrecking bar to remove the board from the screw.

Here's what I do. I use a circle saw to cut in between & parallel to the joists the entire length. It doesn't have to be between every joist, say every 3 joists. Then use the pry bar & maybe a sledge, to remove the pieces. If you have to make bundles for pickup, use duct tape. It's much faster than rope.

What type of head is on the screws? Hex, torque, phillips, square? If the heads are filled with like a solid stain, drag a utility knife through them to break up and expose more of the surface of the screw to accept the bit. If that fails, cut each board parallel to the joists and as close to the screws as possible. Then use the board as leverage to lift and force the screws out. So the cut close to the screws will allow you to lift the board and work on the screws one joists over. Using the board as leverage to ease the force you need to apply.

Get a 2x6 three or four feet long. Using a hole saw drill a 1" hole in the middle of the 2x6. After the hole is drilled remove the guide drill from the hole saw. Center the 2x6 hole over the screw and standing on the 2x6 using it as a guide for the hole saw drill a circle out around the screw.

When the board is removed use a chisel to split the remaining wood from the screw and Vise Grips to unscrew the screw or cut the screws off flush using a Sawzall. If you use the latter method you don't even need to split the wood plug off.
