With any tube developing 8x10, I water soak first, then develop.
However, and this is important, I place my water and / or chemistry in the tube first, then place my film in. I find in the past if I place my film in first then added the water or chemistry, sometimes the film would stick at some spot and I would get uneven development. So take tube, add chemistry, then add film - all in the darkroom of course. : ). It should work fine.
The use of a water per-soak is because you can "burn" - for lack of better words - your negative in a tube due to the constant rotation and agitation. I find for both my 4x5 and 8x10 I have to cut back on the strength of my developer.
My " formula" that works for me is a five minute per soak, followed by 10ml of pure HC 110 syrup in 600ml of water, and then in a tube for anywhere from 8 to 10 minutes, constant rotation, but not all one direction. Remember to reverse every 2 minutes or so. Maybe even every minute is better. Your mileage will vary. Stop, fix, wash etc as per normal
