here's my educated guess... 97

explanation:

of the 156 players, i googled 81 players using titleist (provided that there are no last minute changes). 

i didn't know what  26 players were using... 

so taking some statistics... 156-26 = 130 (sample size) 

of 130, there were 81/130 = .623 or 62.3% players using titleist...

and applying this to the other 26 players,  26 x .623 = 16.2 or approx 16 of the 26 is estimated to use titleist...

therefore the final answer is 81 (known players using titlest) + 16 (statistical estimate) = 97

Not to worry Herman, the time stated is US time, but we are running this competition on Singapore time. It will end at midnight tonight.
