Congrats! I love mine and play it almost daily. I joined the Flash club late last year. In any event, for the flipper upgrade that Vid covered.. post 140... https://pinside.com/pinball/forum/topic/vids-guide-to-upgradingrebuilding-flippers/page/3
I am not sure if it is common, but it is done. I just rebuilt my flippers in the original style and I am super happy with the play... post 294 - REBUILDING 1967-1979 FLIPPERS
Honestly, one of the biggest changes to play was when I changed the inner and outer shooter springs... that turned it into a skill shot as now plunging all the way results in the ball not going through any of the top lane guides to score points and bonus, but rather following through the loop (since there is purposely no gate up there) and right back at you.
As for flipper bands - mine are red and I love them that way. In terms of the post colors, I prefer (and have) the blue (with blue #47 incandescent nearby them) .. this post has an interesting theory...post #35
