New Classic Nordic Skis

I just purchased a new pair of XC skis (from REI), 179 cm. Fischer Spider 62 Crown Xtralite classic Nordic skis. The bindings will work with my current boots. The major differences from my old skis are two:

1. the Fischers have metal edges (full Length)
2. and an aggressive fish scale base under foot.

The advantage of the metal edges is that my control on the steeper downhill segments of Schweitzer's trail system should be much better. Previously those segments could be harrowing under certain conditions. However, I do not yet know if the fish scale base will be as efficient on the uphills as the mohair I currently have. Further, the fish scale base might be slower than the mohair on the glide. Those who ski past me on the trails can see that speed is not important to me. Their laughter seems unkind.

Consequently the verdict awaits my next XC day. There is a cold spell right now, so I am unsure of my next outing. At this point I have accrued just 13 ski days. My arthritic left shoulder requires at least one day's rest between successive ski days. Conditions have been excellent because of Schweitzer's splendid grooming.
