Jeez- chill dude !
I'm sure @Yellowshark is referring to the well-rounded debate on how best to bleed the shocks after replacing the oil - everyone has their own particular method and "swears by it" ! You'll get a dozen flavours of how-to-do-it if you ask the question - that's all he means (as I'm sure he'll confirm). I think all X-Ray drivers have struggled to bleed a reluctant shock at some point!
Part of the enjoyment of this hobby, in my view, is forming your own understanding of the technical details of the car, the best maintenance and setup techniques that work for you.
Everyone has their own experiences and views, and are generally very willing to impart their knowledge. You don't have to agree or accept the advice !
I think the X-Ray's are particularly well designed and manufactured, and have owned and raced them for a number of years. You certainly won't be disappointed if you buy one IMHO. Having said that, all the other "big-name" cars are very good, and capable of winning in the right hands.
