youre skis are 125-105-116 yes?thats sidecut, incase you didnt know
now, lets look at some race skis
my race skis have these dimensions
113-64-102
in 165 they have a 13 meter turning radius.now lets say we increase them to a 105 waste 
we get
154-105-143
now, you just have fat race skis, which probably wont have a 13 meter turning radius, but will turn sharper than what you had.
heres the problem though, 154 shovels? holy shit thats massive, so you need to come up with something in the middle
how about 135-105-126
that will probably turn better
my bridges have
130-92-112 dimensions, notice the much smaller tail helps a bit too, but thats not that important, you're doing good with the "10mm rule"my 177's have a 19m turn.
do what you want though.
