Ive probably mentioned this before, but a small rope tow going UP to the top of the cairnwell T-bar would be an excellent addition, as this would allow users of the Cairnwell Tripple to acsess the bunny run WITHOUT the need for another chair, providing a snow base can be maintained down to the chairlift.
Not this old hair brained chestnut again. In general nobody cable of getting from the top of the Cairnwell triple to the bottom of such a rope two would be particularly interested in using the Bunny run. It's a steep if short red and the Bunny run is a long easy green. So short of getting the dynamite out and reshaping the Cairnwell summit (good look getting planing permission for that) it would be a pointless waste of time. If you can ski off the top of the Cairnwell chair then you can ski directly to the bottom of the Cairnwell t-bar and catch that up if you perversely want to ski the Bunny run.
Further to put in a rope tow you would need to get power to the location because right now there is none, spend time and money maintaining the uptrack instead of pisteing the pistes. Finally you are likely going to have to man it with staff which is an expensive on going cost..
So the alternative is to replace the steep aging t-bar, a type of lift that is widely hated by the snow sports public, with a modern chairlift the type the public like, which means there is no uptrack to maintain and gives easy access to one of the longest green runs in Scotland is a wildly more sensible proposition.
Really there seems to be an attitude of not wanting the ski centres to spend money on improving their uplift on these forums.
