Do a search for Chicago Velodrome or my user name. I bought one and posted some pics. The bag is perfect for holding all your gearing and some tools.

I use the black/blue HKK chain, the cheapest NJS one. Bulletproof. What were you using that broke?

bmontgomery, also consider the KMC K710 or K710-SL. These are about $20-25 and should be at local shops that cater to BMX or Fixed-Gear riders. It's burly chain made for BMX freestyle (which can be hard on chains) but is rated for like 4,000lbs of break force. It's heavier than others, but it's inexpensive, quiet, and strong.
Any difference between the K710 and the K710sl...
I know that the SL is lighter... Wondering if its any real gain- or loss?
compare to the KMC D101?
The K710 is $14 on Amazon Prime right now- so it will al least be my off season chain...

"SL" means Super Light. It just refers to the cutouts in the plates. Instead of having something like 4,000lbs of force required to break it, it requires 3,800, hahaha. It's a great option. I use that one, too.

On the subject of chains, can Pintle chains be considered for racing? Or should those be left for fixie crowd?

Any fans of inch pitch chains and cogs? Anyone use them anymore?

What do you use for a jamming tool?

Do like riding at the front or at the back in a miss and out.

Pretty simple physics; assuming the same wheel speed the tighter the radius the more a chain has to bend so there's more friction in the roller and side plates if they are loaded. Friction = power loss. How much loss and whether that's worth paying attention to is subjective. Thing with going to bigger rings and cogs is you add weight and some aero drag. Balancing that equation takes some time and access to things most people don't have.
My quick mental mull would say bigger is a net gain. As an endurance guy who's lost a gold at Nats by one tick, it's worth paying attention to this stuff, but I also have a lot of time to work on other things. If you had 10 minutes to train, or ten minutes to calc a day, the benefit of the former would be obvious.

Depends on the field. Smaller fields I like to be around the back the whole way. But a big field I will stay up front for the first half. Playing the devil the whole race is a lot of fun, but wears you out. It is good for working on points race skills. So sometimes I will be devilin' as long as I can.
