Questions about AM super shifters

[team 3311]

Hi my team was thinking about doing shifting transmissions this year and I wanted to get some advice about them before we go and put down a larges sum of money.

1. How do you mount them I have seen the pic. and I don't see any mounting brackets

2. what do most people use for the ratios. should we use the standard or go for a optional ratio.

3. Should my team go for servo of pneumatic shifting. Myself I would go with pneumatic but I have been wrong before,

Some background, this is my 5 year in FRC. I moved and stared a team in klamath falls OR. 3 years ago just this season our numbers have tripled. This year my team will most likely go with the kit bot on steroids,(6 wheel drive with 6'' placation wheels). We have limited machining, but we can still make parts if necessary.

If anyone needs more info I will be most glad to share it. Any other advice would be great to.
