I'm looking at getting some new housing+cables for my derailluers and brakes. I run BB7's front and rear, no front derailleur and an XT derailleur+LX shifter. I've been running standard cables and housing for the past 2 years, so I know no difference. I'm looking at the Delta Aztec Powerlines and the Jagwire's Rattler MAC. I can get those at wholesale, so I'll end up with one of them. Opinions on either? Will I notice a difference going to one of these from regular housing+cables?
Thanks for you help as always,
