Before you spend any money on a new blade try this technique when cutting plywood.
1) layout your cut lines across the plywood piece.
2) run painters masking tape over the cut line on both sides of the piece (you can mark the edges of the plywood piece to line up the cut when the cut line on top is covered with tape).
3) Cut with your current Ridgid blade.
Unles you’re doing production carcass work, the few extra minutes it takes to apply the masking tape definitely should solve the problem. You may still have to use this techique even with a more expensive blade (I have a WW 2 in my Unisaw).
Another technique is to oversize the plywood piece by 1/4” on all sides and clamp a straight edge along each side while you run a bearing guided straight cut router bit to cut the excess. This will also eliminate splintering, and you don’t have to tape the edge you’re routing.
