There are 2 schools of thought on this. There are those who feel the pros should be prohibited from playing the regional tour circuit...that the circuit is for up-and-coming to hone their skills and sharpen their teeth and try to qualify for the WPBA. But some feel that the pros should be allowed to play...and if the up-and-comers aren't skilled enough to compete, then they aren't ready for the WPBA anyhow.
I, personally, subscribe to the 2nd school of thought. If there is a player competing at the regional level who is skilled enough to compete and make her mark in the WPBA ranks...then playing with the pros in the regionals isn't going to matter. Iris Ranola is a perfect example. It didn't matter to her that Tiffany was playing, because she is ready to move to the next level.
To be honest, there have been some players in the past, who have come from the regional tour system, who did yet play strong enough to compete at the pro level. Perhaps, if pros had been allowed to play in their regional tours, these ladies would have seen what is needed to be a top competitor.
I sincerely hope that no one takes any offense to these comments. They are not intended to slam any individual or group of individuals. It is more a commentary from someone who came up through the regional tour ranks...who knows what it takes to earn a place in the WPBA...and who, in her RT days, would have welcomed the challenge of playing a pro before she got to WPBA.
