The CSM looks heavy. At least 1.5oz which is what the old school builders used to use (ie. lay one layer of CSM and then a layer of 24oz Woven roving into that.) CSM wasn't designed to be used by itself, the resin to glass ratio will be too high. Woven roving isn't as good as the non woven 1708 fabric due to the crimp

Look at it another way, all V-20's were constructed using CSM and woven roving for the hull and stringers. The liners were done with a chopper gun and reinforced as necessary with roving.
