Planned on using the strobe cables for power and ground and syncing. So now because it would look best synced. What flasher would you guys recommend? Ulf22 or 44?
Yes, you can definitely reuse the existing strobe cable. It's more than capable of handling the demands of the LED lightheads you're proposing. You will need one wire for ground, one wire for power, and since it's there, you can use the third wire for low power.
With 900-series, 700-series, and 600-series LEDs, you will need to use an external flasher to synchronize the LED lightheads. This is by no means a bad thing; quite the opposite in fact. The existing strobes operate from one or more centrally located strobe power supplies. The same will be true of your LED upgrade.
All of the strobe cables already run to one central location. Your work is cut out for you. Just set LED lightheads to steady burn, and let the LED flasher do the work, just as the strobe power supply does now.
The ULF44 is a superb flasher, and I would definitely recommend it for this application. Although it can handle more, I prefer to maintain a one ULF44 to four LED lighthead ratio. The increase in cost for an additional ULF44 or two is far overshadowed by the increase in configuration options afforded.
The ULF44 has two flash pattern memories: one main flash pattern and one override flash pattern. With this, for example, the LED lightheads in the intersection warning position could override to a rapid single flash during calling-for-the-right-of-way mode. Further, all of the LED lightheads could be made to revert to a slower flash pattern during blocking-the-right-of-way mode.
