I cant comment on the discs cause I think you will need to purchase new wheels or at lease hubs and spokes and that can get $$$. For a weekend warrior like me I cant be happier with the RS Tora 318 Solo Air. Absorbs everything I've thrown at it from jumps to rockgardens but im a beginner. I hear changing out your brake lines to Jagwire or better Gore Ride-On and it will feel better than new, of course get new pads too. Good luck
