Speaker Support - Three Feet or Four

I'm thinking of going to a three-point foot system for my Gershman Acoustics Sonogram floor standing speakers.

Reason for doing this is that the hardwood floor shifts with the seasons and a four-point system can require adjustment throughout the year.

Each speaker weighs 63lbs, has a baseplate footprint of 10.75" wide and 16" deep. The basplate is 0.5" larger all around than the actual speaker cabinet

I believe the centre of gravity to be just below mid height and relatively centred from a footprint perspective.

I plan on mounting the two feet that levels the sideways attitude on an outrigger.

Are there any advantages to placing the outigger feet at the back or the front?

or is this just a matter of using the best config for stability based on centre of gravity?

Is there any advantage to having the feet equally spaced or use the maximum distance possible within the confines of cabinet footprint + outrigger dimensions ?

Or should I just stick with four feet?

Note: I don't have to worry about kids or pets bumping speakers :-O

Thanks in advance
