Not so fond of the new Speed Merchant (ala Trinity) front end. It may be super adjustable but to dial in those adjustments I would need to get a 1/12th setup station. Already got one for 1/8 and 1/10, don't want to have to pickup and lug around another just for 1/12.
What is nice about the old school is that all you have to do is install the proper spring, shim accordingly for ride height and caster, check tweak (the old way of lifting fron the center of the rear pod with a knife to see if both wheels lift at the same time) and your done.
Right now I'm swaying towards the reactive caster cause its not extremely old but not new either which is what my budget can afford for now.
