Replying to Waist size?

so i’ve been riding line’s sir francis bacons with a 104mm waist on them (i think?). it’s the only pair of skis i have and got real comfortable riding them all-mountain.

just recently i was thinking of picking up a pair of 108mms. the skis are 100-200g heavier but the turning radius is the same.

my question is, taking all-mountain into consideration, would one have a hard time skiing all-mountain with a pair of 108s? would it be any different from 104s? suggestions would be great as i’ve been hearing a lot of different answers from a lot of different people.
