I have them both and well I tend to lean towards the Lx2 It is a little more rugged and well the way I race them both the LX2 seems to hold up just a bit better than the Hyper 7. ( LIKE YOU SAID BOTHE HAVE SOME ALUMINIUM HOP UPS ) I am not dismissing any other rc out there like Associated, mugen or any other kits like that. I have driven them all and all are very formitable and comperable to one another. I myself am an Ofna guy like I said only cause of personal experience. If i were to give you advice on which to buy I would say the choices you have brought out are without a doubt Great choices indeed. So feel comforted in either one you choose will suit you well in bashing or racing. Hope this helps
