Tunze Stream magnet holder?

[MNSPS]

I'm going to be ordering two 6100 Streams for my 150gal tank today. I'm trying to decide between the 6080.50 and the 6200.50 magnetic holders. The tank has 1/2" glass. I just want to make sure that the 6080.50 will hold the 6100 securely even if I bump into it. Is there any reason I shouldn't go with the stronger 6200.50 magnet holder? Is there any greater risk using the 6200.50 magnet holder on 1/2" glass?

you have to be more careful when installing the larger magnets as there is risk of breaking glass; you are told to slide them together whilst they are touchign the glass.

As Anthony said, the 6080.50 is really plenty strong.
