Agreed. I've been using the Ti/Aluminium screw kit's from RC Champ for ages
1) the look great (all anodized blue on the top

)
2) they are about as light as you can go (unless you go full alu, which for high load areas is a no-no).
Bascially, the underside of car is Ti, and the top in the blue alu. What it does mean is that any weight I take out of the car can be put back in ballast... which can a) lower the cg and b) give another tuning option
If you take a 10g out from the topo of the car... and place it down on the chassis... instant improvement. Obviously, I doubt anyone but the best can notice a difference, but there still the psycological advantage of having done it....
