3" Superfeet with regular front rest.

Is there a down side to using 3" Superfeet with a regular front rest? I have used a set of Dave Dohrman's 2" Superfeet with my Farley rest for years but seen some people using the larger feet intended for rail guns with front rests and wondered if anybody could tell me a downside to using the 3" feet? It seems like a good Idea but sometimes I overlook reasons why something is not a good idea.

This thought came to me while reading the "Mandatory use of Superfeet" thread, and I was going to post my question there but decided it was really a different subject.

I have some larger diameter disks that were not by Dave, and although they had a different material on their bottoms, I would guess that the issue is unit loading. If you load them two lightly, they might not get as much traction as the smaller size, but this is just a guess. Perhaps someone has tried the exact combination that you are asking about. I modified my disks by radically reducing their bench contact area, and changing to a thinner material that still had good traction characteristics. In their new configuration, they seem to work very well. Dave told me that when he first built his Super Feet, that he had tried a thicker material, but that targets showed that this was not desirable, so he changed. This was in the prototype stage.
 
The only problem I have had with the larger diameter superfeet with front rests in on ranges with short (front to rear) benches. This is usually with the longer Scoville stocks. They force you to set your rest further back on the bench then you might want. I have also had problems with my rail gun on narrow (side to side) benches. One of the discs may hang partially over the edge of the bench. It depends on your rest design and rail gun design and how they interact with the bench design. Given the later my best ever 10 shot agg. was fired with one of the rear superfeet partially hanging over the edge of the bench. Tim
 
I would like some super feet that are about 1" diameter with 3 points on the bottom... and a small center drilled in the top.... Hmmm
 
I actually have a set of three triangular metal feet that have three points on the bottom and a small center hole that John Pierce made for me (and another set for Bart) about ten years ago or so. Bart had the idea of having these made to battle the irregular bench tops with our rail guns.

I never really used them; perhaps I should have used them in 2004 at Kansas City, but they were most likely in the same spot of my loading box then where they are today.
 
Remind me again, except for rail gun use, whats wrong with the leveling/isolation feet used with lathes?

(Aside from having to hire an urchin to clean the bench, which you need with superfeet anyway...)
