High Torque motors?
 

i have a CYMA M14 with Element 210% spring(460+), and G&P 10.8v 3300 mAh battery, along with an Element Hop-up unit, Element H-nub and Guarder clear bucking,
for a motor im undecided as to go for a
Marui EG700 SHORT, which ive heard a good bit of praise for

or

Guarder Airsoft INFINITE Torque Up Motor SHORT/
G&P M140 HIGH TORQUE Ultra
which i havnt heard a lot about,

has anyone got any experience of anyof the above in contrast with the other motors?
