Glassing the center section is usally a good idea but in this case I must disagree. Other than the elevator counter-balances which are weak and need carbon reinforcement, the weak link on a Laser 3D is the fuselage. It is weak in the area right in front of the canopy where the ply fuse sides are at their most narrow. Use your glass cloth or kevlar to reinforce between the fuse side and the doubler in that area, actually the whole doubler could use that sandwich. I can speak from experience, I broke my fuse in half doing a vertical "wall", ( straight down and pushing at idle)it was quite a shock. I was asking for trouble and am not blaming anybody but myself but it did expose a weak area.
