The primary reason I was told (by a wiesco rep) not to use a ball hone, when it is spun in the cylinder bore, it drops into the ports and as the balls come out they snap against the cylinder wall and can cause pitting where the ball mnakes contact with the wall. NEVER spin a ball hone fast, that will create havoc on your cylinder. If you must feel that you need to deglaze, use the brush hones Wiesco offers, and only make a token pass
Jeeks:
I'd like to try one of those brushed you talk about and compare it to a ball hone. I've had the same ball hone set (125's & 250's) for years from Snap-on. I think the "ball snap" you speak of is probobly over thinking the situation. Even if it did occur, it would be on a microscopic level. And I can't see how that would affect a 2 stroke engine.
Anyway, the ball hone process only takes 10 seconds. It's not like your siting there for 45 minutes spinning the thing.

here's the wiseco link for the bruch hone.

The point is it can make a chip in the plating, this wil give a foot hold to start damaging the cylinder plating. Obviously your going to do what you think is best, and I'm going to do the same, for me, I don't use a ball hone, either, nothing, a brush hone or a rigid hone in that order.
Jeeks:
Yes, I read that, thanks. I wonder what RPM range they recommend? Like I said, I'd like to try one on the next rebuild. I mean, let's face it, this is what they do. I know what I'm taught.
