standerd LC springs or millners 20% uprated

[123-gtt]

Hi having a problem trying to work out what is the better springs for my truck,iv just bought the milners LC 20% stronger springs,now im thinking to send them back,as maybe there not going to help off road as they dont really fit very well,and will take away the articulation,and will start to kick its wheels in the air before needed,has anybody got any feedback on these thoughts,im i better off with the standerd LC spring as these fit better and will articulate more?
cheers alan
