My best advice is to get a nice soldering iron/station and learn to use it effectively. Take an hour and practice tinning some wires. If you don't have any spare wire, use the crap wire that you cut out of your stryfe.
Have you decided on a battery type? Are you planning on upgrading motors?
If you do the smoke trick, won't it gum up the gun after a couple shots.
I shot only a half dozen flour darts from my Jolt and yeah it was gummed up on the inside of the barrel. I've lubed my Jolt with lithium grease when I bought it, so it may have more lube than most factory blasters, so YMMV.
