Man its been a long time since I've been "in the know" with the B44.1 now I have questions

1. I heard people are putting Kyosho big bore shocks on their B44s. What size shocks are they using? Just the standard RB5 shocks? Are they really that much better than the new AE shocks? Do the rears only fit if you use the outer hole on the shock tower? I ask cause I bought my B44 used and the chassis was a bit messed up (screw holes twice the size than org.) so I converted it to a B44.1 just kept the old shocks and now I wanna upgrade.
2. I seen the new Jconcept wheels and they look amazing but my concern lies in the weight of them. I may be way off here but with the 2 pieces and it bolts together it just looks like it may weigh more than the AE wheels or the Jconcepts rulux wheel. If someone gets a set of the new Jconcepts wheel and can weigh it I'd be interested in knowing how much it weighs.
