WSF does have better stamina, but XF can hold the stall pattern longer.
No, there's not a very good substitute for it, because You'd need something that wouldn't cover the contact points, wouldn't slow down the combo, and something that can still generate attack power without having a loss of a lot of stamina.
Girago wouldn't work, because it covers the contact points. Goreim slows down the combo and doesn't have enough smash.
So, no there's not really a real substitute for the combo, your best options might be Bahamdia or Girago. IMO
