The Ladies Spirit Tour is "sort of" an amateur tour, amateurs can play, but it is also a stepping stone to the WPBA tour - and they are WPBA sanctioned. Anybody (female) can play in a LST event - pro amateur - or whomever. The ladies are fighting for a qualifying spot - and frequently you have TOP PRO PLAYERS competing on the LST such as GYK, Monica Webb, Helena Thornfeldt, Tiffany Nelson, Jeannie Seaver. Everybody understands that some pros will show up to these events before they pay their entry. So it is hardly an amateur tour.
In contrast, you cannot win a WPBA Qualifier on the KBP Tour, and you will not see any pro players, or many regional tour players that are not on the exempt list.
I have seen both Yu Ram and Bo Ram play, and they are most definitely more suited to play on the Ladies Spirit Tour. I think that anybody else that has seen the difference levels of tournament play here in Florida (Amateur-Regional-Pro) would say the same thing. I am not saying that they were wrong for allowing her to play, I am just saying that the end result proves that she should be playing on the regional tour level. I hope she makes the move to the LST, I think both Yu Ram and Bo Ram would be a nice addition to the LST, IMO the strongest "regional" tour you will ever see.
