Don't mean to encroach on your tread, just a quick q.
I have been riding a ski-doo mxz with 96 pins and stock runners.
This year (YES I jumped to Yammi) I am getting the Apex ER and I have been suggested to changethe runners to Woddy:s duallies 6"no studding.
Then someone told me I should get the 6" duallie and no studding.
I ride fast and aggresive, always on trails, lots of wooded trails...etc.
I don't want the feeling that I am riding on a train track, but want safety so that I can ride aggresively enough. Any tips would help.
