I think this is a much simpler problem than fins or angles or anything else - it's likely that you're simply arching your back too early and stalling the board before you've properly caught the wave. A shortboard won't lift by you paddling alone (that's entirely weight distribution), and if the wave is doing it, well, you should already be popping up.
So, yes, paddle faster, but also keep your head down (plus the inevitable extra paddle) and keep the nose of the board down until you've caught the wave.
Also, be aware of what your knees are doing - as you arch your back as the wave hits you, its easy to put too much weight through your knees and stall the board.
