hi guys, i personally think the chassis is one point that should not be changed at all, the graphite chassis in my opinion has proven to be extremely strong and obviously lightweight and flexible, i have had and seen hits where i thought this must be game over only to see no damage, this is why i race Xray , durable and lightweight, please Xray keep this the part same.
cheers

p.s judging from my experience i would prefer graphite over cf, but this is only my opinion
