Find a speed and revrate that you're comfortable throwing all day. Also make sure to take the time you need on the approach. Not just preparing for the shot but also not rushing the foul line. The increase in power is just not worth the inconsistancy that it can create (This has been one of my downfalls for quite some time).
I've reduced my strike shot to about 15mph with low revs and my hammer still manages to blow the pins off the deck
