Something handy is to run the main sail halyard through 2 holes in the mast at about 1m from the bottom. There the halyard comes out of the mast and a couple of centimeters later goes back in. This enables you to stand at the front beam to rig the sail and still be able to pull downwards at the halyard. Saves time as you don't have to walk back and forth all the time.
Also the daggerboard pull up system installed on the Falcon and Blade is handy (I dont know if your boat had it already).
A seperate tack line is convenient indeed as it gives you time to steer in between the hoist. Same for dousing.
Improvement between the Blade and Falcon is the tramp allowing you to run things below it from the side (I don't know the Viper/Stealth tramp setup). In that way you can run lines to the side stay and then bungee them below the tramp. Clean!
