Was wondering, know pretty much everyone goes for multi layer these days and i know different builders prefer different ones ie cometic, raceline or proper WRC ones etc but how come not so many ppl wire ring blocks and just use a group a HG these days?!?!

Know its kind of an oldschool way of doing it but as far as reliabilty goes is it still reliable but just not used these days due to metal ones being availble?! Or were there problems with doing it.

cheers for any info
