Thanks to my niece I am getting back into lego having not used much since the 90's so studless beams are all very new to me.
I still have loads of vintage technic stuff the prize set been the 8860 car, all the parts are mixed up now so would struggle to fully build it again. Just bought the 42095 power functions remote racer and a few other bits and pieces on ebay (extra studless beams, steering rack, servo motor, balloon wheels and differential) to update my collection. Went for a studless set over the 76112 Batmobile as I already have a lot of the old studded parts.
Loving the new construction options the studless parts bring but will keep mixing with old parts in my own builds. Not so bothered about looking realistic or clean, just like experimenting with different wheel setups etc. I find the old studded parts better for random embellishment with classic lego bits which my niece enjoys.
Edit: I'm envious of all the elaborate suspension setups posted on here. Don't think I can manage much more than the setup used on the 8860 with the parts I have. Is there any cheaper way of getting started with the custom hubs, ball joints etc rather than buying another expensive kit like the 42099?
