I built a Wildman Eagle Claw. Nice kit, fun to fly. Loves 2550 motors.
Some thoughts: you don't sound like you are going overkill for this kit - you ideas at the top seem reasonable. I went with 25' of 9/16 TN for the apogee, and 15' for the main. I also like ubolts better when there is space for them, since they can't unscrew themselves - though there are other simple things you can do to prevent this. I use the nosecone interior for my tracker. Good place for it, keeps it away from the altimeters. I use a 84" Spherachute for the main (my rocket is 16 lbs without motor), and a large enough nomex for a burrito - space is a little tight, but makes it without too much trouble. I also use 3 2-56 shear pins to hold the nose cone on. I used extreme rail buttons, but std buttons will also be fine. Like it appears you are planning, I also use 1" kevlar strap leaders near the charges to avoid burn damage to the TN cords. I also like to cover/wrap the charges with small bits of sacrificial nomex or kevlar attached to the cords to stop the worst of the hot particles before they even get to the chute protectors.
What is the descent rate you get? I just ordered a 96 inch Spherachute for a rocket that I expect to be 15 pounds empty.
What I did to correct this was to sand the ID of the tail cone so it would allow the OD of the motor retainer to fit inside the tail cone. Looks pretty cool like this ....
I did this too, for cosmetic reasons. Don't remember the motor tube being too short. I did trim a bit (1/2"?) off the tail cone though so the retainer shoulder would fit inside - this way the OD of the retainer ring is about the same as the boat tail, so it does not stick out into the airstream.
My first surprise was that the EAGLE CLAW 4 KIT Fiberglass components nearly weighs 12 lbs.
NOW WHAT!?!?
Guess what I got today... Guess what issue I found today...
Giant Leap - 54mm QWIK-LOK System
View attachment 182689
It doesn't fit the FG MMT... I actually got it to barely start down the tube, and could probably pound it the rest of the way. But, that does leave any room for what I believe is a requirement. EPOXY.
NOW WHAT!?!?

Working with a set a calibers, the best I can tell is the MMT OD is equal to the ID of the retainer at 2.280". It is possible that the MMT is .002" bigger that the retainer. Or, .0005 smaller.
It is too difficult to tell using my calibers.

The Qwik-Lok Retainers OD is 2.464"
The Boattail Aft ID is 2.400.
If I stick with Qwik-Lok, I too want to recess the retainer nearly the entire way up in the boat tail.
