I use a 81 spur of 48dp, no problem. For me, the more fragile part is the blades (pin protectors), i use 8 pairs, it not espensive.
Positive, is more Strong, cardans, diffs, belts,...
Negative, i´m not sure is this is a negative point, is more innovative, some parts are slighty different, roll bars, steering,

Gansei, do you use original springs, and roll bars, and the track have high or low grip?
