Handling are relatives. Vees are always easier to handler in rough water and high wind. Hydro on the other hand prefer less wavy water.
But UL-1 has fairly large body, so handling in 4" wave should not be big issue. But Vees are easier in turns.
If you want something fast and only need medium capacity 3S Lipo to run, take a look at the Starship from MiniCatUSA.
The can glide on 3 - 4" wave at 50+mph easy.
