It looks like you have lots of power. Do you need that much power? Is it safe? Is it consistent enough? How large will the final shooter be and how much will it weigh?

Wow, haha. A.) Yes, this was the amount of force calculated to get us scoring the high goal. We may have to modify once we get a shooter on the bot, but until then those are the rough specs. You can never have too much POWAAAAAAAAAAAAA. B.) It is safe, sort of... I wouldn't want to stand in front of it, but it has never come apart or exploded. C.) It is very consistent actually, again, we are still tweaking, but once we trim those guides a bit more, it should be even more consistent. D.) I'm not sure on the final design, although it is fairly compact, and is designed to sit in the middle of out bot, which is not that big if you watched the frame assembly video. Total weight, again, I'm not sure, but im gonna take a guess at about 15-20 lbs. I'll try and get a better measurement today.

I feel sorry for the robot that tries to block that shot.

Same,

Same,

Are you sure your shooter structure is strong enough to last a whole season? People have been seriously injured when changing the coil springs in their car and they were not using the proper equipment/techniques for compressing the springs. While it may be fun to build an overpowered mechanism, it is poor engineering practice. It will also cost you in terms of weight, space, reliability, risk etc. A local team had a similar shooter in 2014. It worked well but the team members were too afraid to work on it and they replaced it with a different type of shooter that did not use large springs.

That is a whole lot of power! I like it.

While in general I agree with your sentiment about safety - I do think the word 'overpowered' could be a bit of a leap if there goal was to fire the ball in as straight a line as possible. Maybe this is their goal...

How straight does it need to be? At some point, one passes the point of diminishing returns. A mechanical failure in a mechanism with that much stored energy is not very funny.
