I will predict if you say me the roster of your team for the matches because Bulgaria will be without some of the strognest players - Evgeni Ivanov, Vladimir Nikolov and captain Plamen Konstantinov. I want to 2 wins but maybe it will be 1-1 wins between the teams, of course i think it will also depends from Bulgaria - Spain and Finland - USA, mainly mentaly will depends. But of course you have to tell me USA's men team list, please. 
Good question! I do not think the USA will be playing all of their top players throughout the World League either. As you know, the teams do not have to submit their 12 player rosters until the day before the first match of the weekend play and can change the following weekend. However, here is the list of 19 players the USA has to choose from:
1 Lloy Ball (S, 6-8, Woodburn, Ind., Indiana-Purdue, Fort Wayne)
2 Sean Rooney (OH, 6-9, Wheaton, Ill., Pepperdine)
3 Evan Patak (Opp, 6-8, Pleasanton, Calif., UC Santa Barbara)
4 David Lee (MB, 6-8, Alpine, Calif., Long Beach State)
5 Rich Lambourne (L, 6-3, Tustin, Calif., BYU)
6 Phil Eatherton (MB, 6-9, Glencoe, Mo., Ball State)
7 Donald Suxho (S, 6-5, Korce, Albania, USC bv)
8 Reid Priddy (OH, 6-5, Richmond, Va., Loyola Marymount)
9 Ryan Millar (MB, 6-8, Palmdale, Calif., BYU)
10 Riley Salmon (OH, 6-6, League City, Texas, Pierce College)
11 Brook Billings (Opp, 6-5, Santa Barbara, Calif., USC)
12 C Tom Hoff (MB, 6-8, Park Ridge, Ill., Long Beach State)
13 Clay Stanley (OPP, 6-9, Honolulu, Hawai’i, Hawai’i)
14 Kevin Hansen (S, 6-5, Newport Beach, Calif., Stanford)
15 Gabe Gardner (Opp, 6-9, San Clemente, Calif., Stanford)
16 Brandon Taliaferro (S, 6-5, San Clemente, Calif., UCLA)
17 Delano Thomas (MB, 6-7, Sacramento, Calif., Hawai’i)
18 Scott Touzinsky (OH, 6-6, St. Louis, Mo., Long Beach State)
19 Alfee Reft (L, 5-10, Oxnard, Calif., Hawai’i)
Even the Finland coach stated he was going with a try many younger players as he prepares for the future European championship play.
