In planning the build I've run into a couple of issues, static ports located on or near the nose cone are not recommended for a barometer based altimeter and were to locate the av-bay switch. What altimeter are you using and were did you mount the switch? Any clearer photos of static ports and switch location?
Are you using motor ejection for the streamer/drogue deployment? What's the purpose of the second ematch, were is the charge attached?

You've raised several good questions. I can give you some answers for this specific rocket. They may or may not apply for yours.
Static ports near the cone aren't ideal. However, there are two things to consider. First, at the points in the flight where you need good data (i.e., at apogee and at low altitude deployment), the rocket isn't traveling very fast. At those times, the altimeter is producing good data. Second, some altimeters have ways of avoiding getting spoofed during portions of the flight where the altimeter data might not be accurate. The MAWD, for example, has an explicit mach delay, and the quality of the altitude data during that delay doesn't matter. For this rocket, I will be using a stratologger because the altitude is above the capability of the MAWD. My understanding is that the stratologger will be calculating what is essentially a smoothed velocity value from the altitude data. I'm reasonably confident that the altimeter will be able to figure out its going really fast early on, and not deploy an apogee charge until apogee is actually achieved.
The photos below show the current setup. The first pic just shows the overall layout. The cone is off so that you can see the altimeter skid. There will be a beeline tracker skid there as well. I have modified the setup so that the chute is on its own short piece of harness. The apogee charge (in the "masking tape" container) sits just above the motor and then the bulk of the harness length goes on top of that.
This rocket is designed to fly over 30K feet on motors such as the L935 or K300. It's not possible to use motor ejection (the delay is not nearly long enough). The apogee charge is electronic and just happens to sit about where the motor ejection charge would have been.
The second pic shows things after packing the separation charge and the harness. This picture more clearly shows the position of the screw switch at the base of the cone (its an Aerocon PVC screw switch). At the pad, the switch is turned on and the cone is set into place. Once continuity is verified, the shear pins are inserted and the rocket is placed into the tower. I've used this approach on many 2" rockets. Note that the large hole in the side of the cone is for the hardware that holds the bulkhead in the cone. It's possible that apogee charge pressure could get into the cone through these openings and potentially trigger the "main" charge. Therefore, for the actual flight configuration, these openings are covered, as is the opening at the base of the cone where the ematch wires emerge.
The third photo shows the locations of the vents (six total, three into the tube below the cone and three into the cone shoulder). The vents on the left side of the picture vent the airframe section only. Then, there are three pairs of holes higher on the airframe that have matching holes in the cone shoulder. For each pair, one hole is a vent into the cone and the other is for a shear pin. The fourth pic is with the nose cone inserted. The cone is a nearly exact match in diameter with the top of the tube (which I hope help to avoid turbulence that might spoof the altimeter).
The last pic is a drawing of the rocket with the 6XL case. I'm probably going to need a smaller chute when using that case. There's not much room.
