RG, thats true, the low ohms will burn the points.
I did the conversion after I burnt up one of my stock coils. I used an old Harley coil. It is one of the oil filled chrome cans with two outputs. It has the same screw on caps the hold the plug wires to the coil as the stock points coils.
It was cheaper than getting one stock coil. I didn't use it long. The lobes weren't ground the same, about 5 degrees apart. With the timing light I got timing marks. One mark was to the left of the stator F marks and one was to the right of the stator marks. The stator marks are about 3 degrees apart. There was a noticable amount of room between the F mark and the flash to add a degree on each side.
One set of points is easier to gap and time than two, but the difference in timing I didn't like. I guess if you figured out which lobe was off and you ground them to match it would be a good deal. I couldn't even scratch fine with a file. So I went with the Pamco.
Best thing I ever did for the bike. Well, that and the 750 kit.
