Hey anyone have a suggestion on combo skis for my little guys? They are 7 years old and can get up long line on those radar jr skis that have the bar for the tips and a tie for the tails. They can also take the bar off and get up, but the tie for the tails takes a screw driver to un hook and I haven’t tried that....Should I unscrew that thing that keeps the tails together or is there a better way to go? Or just keep blasting them around without the front bar? My kids only weigh about 50lbs.
