Building a ski lift?

Here's the back drop:
An insatiable love for skiing, lives in the center of Saskatchewan. The Canadian prairies putting 10 hours between Me and the nearest mountain.

This means when I do head out i usually stick to big mountain skiing and stay out of the park for fear of cutting my trip short with a broken limb.

With skiing being so far i figure i can bring the park home to change it up. With a couple decent hills on our farm i think a 4-600 ft "J bar" lift would make for some short glades skiing and a small park for practicing. I built a 200 ft rope tow for a bunny hill of sorts last year; it's only got the juice for one skier at a time and the hill is pretty flat.

So for questions:

I was looking at about 10 feet/ second for lift speed. Any thoughts on whether that will be too fast?

A 6 foot bullwheel will leave me with close to 3000 ft lbs of torque at the center to pull 5- 200lb skiers up the hill. Not sure if if 3 feet from cable to center of tower will be a little tight on the way up. I havent got a clue what most t bars are for width. Opinions?

Open to suggestions on construction/ alternatives to a j bar.

Thanks!
