rw99banshee

First off hello. First post here. Finally got a banshee at 38..lol. anyways my suspension is quite subpar as we all know on these stock machines. I am a big boy..260 and this thing rides horrible for my weight. So I was looking at 2 +1 with ball joints alba and others and a set of fox floats. I like the idea of floats as I will be 70% dunes rest trail and want the adjustability. Will they hold up to my weight? End result for this bone stock bike will be 70 to 80 hp all around toy. Not really into jumping just want smooth ride and good handling. Second is rear. I'm thinking plus 4. If I revalve stocker is it decent? Again very little air time for this guy:) Thanks guys
