"That again is
only ones opinion. In my opinion and experience....Running martingales don't
work well with the S hack and it is not teaching your horse...... they learn
to rely on them. They have a constant downward pull then to the
hands."
Once I am assured my colts will not drop their
heads and go to bucking on me I put all of them in a running martingale with a
snaffle . I usually ride them in one for a year or two and then take it off , I
have never had one learn to rely on the martingale , all I have ever had it do
is help teach them control/collection . To me it taught them good habits from
the start , 99 % of my riding is on trails and in rough country not arena riding
. But like you said , this is just one persons opinion .
