Is it safe to assume that all touring pros will be present at all NT events?

For example Dave Feldberg, Avery Jenkins, Nate Doss, etc...

There's an NT event in Michigan this summer and I don't want to miss it, if for no other reason than wanting to see these people play.

short answer..."no"
but, MANY top players will attend as it provides ^ $$$, ^ points and sponsorship bonuses...

i just played with dave in taiwan and his agent helps organize events/travel plans. being from michigan, pretty sure he will make that event you are talking about.
he was given a sweet deal to fly to taipei for the event...he spent like 20 bucks for the entire week (including airfare,hotels,fun)... me=jellus

there are 126 eligible touring pros as of march 15th from all parts of the globe.....it would be near impossible to get them all at one event.

take a look...

Need me an agent to organize trips and things to do for my wife so I can get away to tournaments
