I recently built one myself. It was my first medium power build. Fun build. I had started a build thread but had problems adding pictures.
I put a baffle in mine in the lower coupling and attached an eyelet to that. I put a swivel on the eye, then some kevlar thread, I got a snap swivel where the chute attaches as well, so I can easily remove the chute for whatever reason. I saw on one thread something that looked like a ball on the shockcord to prevent zippering, I am gonna have to come up with something like that.
I put a plywood bulkhead and an eyelet in the uppermost coupling so the rocket will separate there (right above the lower purple ring, midway up the rocket in the pic). That way you don't even have to worry about the eyelet on the nose cone at all. I used filler on the fins to get a nice smooth finish but used too much water and warped em. Then had a heck of a time straightening them back out. Bungee cords, a hair dryer, a sponge and finally a clothes iron. LOL
For me the worst part of any build is filling the dang spirals. I am working on Super Alpha and decided to try something different. I watered down some filler and covered the entire tube with the stuff using a foam brush. It sanded off much easier and smoother. Of course the Alpha is much, much smaller. The (somewhat careless) sanding fuzzed the ends of the tube a bit as well but nothing I can't fix. I can't really recommend using that method as too much water will probably damage the body tube.
Here is my baffle. Its a cardboard core from aluminum foil and some homemade plywood rings.

I left the rear centering ring off so I could put my fillets in that way. I put them where the fins meet the motor mount AND where the fins penetrate the body tube. I also put fillets on the outside for cosmetics. I used some wood filler with a little Mod Podge mixed in. Looked kinda like tan Bondo when I mixed it. It made nice looking easy to sand fillets. I taped the fins to get uniform fillets and keep my excess goo off the fins.

Then a little sanding:

I painted it stock. The red pinstripes gave me fits but I finally got it. Here is (nearly) finished product. I use the cheap acryllics from WalMart or Hobby Lobby then gloss it with automotive clear coat. I still may do some wet sanding and another shot of clear coat. And some stickers or decals. Hope this isn't considered hijacking.
