Salutations Earthling racerdx6,
i do prefer the rev3 myself, especially if it uses the old skool front end.
b'cos ....its simple beyond words!
easy to build, setup n maintain.
and there is very little chance settings being altered in a scrap.
as a matter of fact, when i purchased my carpet knife, i installed the old skool front end right away!
1/12 should be run on smooth prepared tracks , so i feel a strut sus shld never really be neccesary.
