For the first time in almost 1000 miles I experienced some head shake with the TS skis yesterday. Up until now they have been almost perfect but yesterday the sled wanted to make sharp quick movements in certain snow conditions. Turning the carbides to 1 helped but didn't stop the movement completely. It seemed very aggressive, not a true darting but a mini dart if you will. The trails at camp were hard and thin with lots of ski marks. When I got into better snow it seemed to go away. Last night I got a call from my neighbor who purchased a 1200 enduro two weeks ago and he experienced the same mini dart and was wondering what he could do to about it . we are both running the 5 inch carbides. I guess I spoke to soon on how good these skis are. They are good but not perfect. Cant run any less carbide showing so I guess I will have to live with this in those conditions, which are less than great for sure.
