I am using The Blade XLT adjustable ski. Keel is identical to Blade XC, which I have also. I am using 6 inch 60 degree shaper bar carbides made by Stud Boy. I find very light steering with exceptional bite and minor darting. Minor push turning in a field with 8 inches of fresh snow. Skis are very predictable and build driving confidence when riding on a tight twisty trail. This report is with 40 miles and trails in acceptable to good condition. The keel is the same on the Blade XC and Blade XLT. Only difference being the mounting for the ski can be moved forward or backward from center position on the XLT.
