I control my lpro101 with trimble thunderbolt .
now is more then one month , work good very stable .
But I am not happy , sure long time is more stable of original 
thunderbolt with ocxo , sure is more stable in holdover ( we need in 
holdover ? i never lost gps signal ) .
But short time is worst then original ocxo . I have 4 lpro101 , all four 
have short time as datasheet near 2.5 E-11 .
Maybe I am not lucky and my all lpro are not the best in short time , 
but because my primary interest is short time , I  need to drive my 
spectrum analyzer and my microwave generator with clean and stable 
reference , the lpro not respond to this needs .
I may send plotting at 12.8 GHz with ocxo and with lpro , there are to 
much difference.
I think you need to control your LPRO only if you are interesting to  
control the drift of your lpro and use it as reference only for compare 
, but not for drive microwave instruments.
regards Alfredo
