You had mentioned "basic trials" so thinking you were referring to Normal or Hard, not Extreme, is understandable.

Since we don't know what standard you use when you judge their ability as "decent", it's hard to say how well things would go at minimum ilvl.

I would ask how "failure tolerant" your friends are. Some players rise to the occasion when they hit a wall. Some get easily discouraged.

If they're the former, go ahead and give MINE a try for the first clear. If they're the latter, I'd start with normal syncing then switch to MINE if they are clearing as easily as you think they will.
