For a crunchier and less syrupy pastry, use half the syrup. Traditionally it uses Pistachio nuts but I prefer the taste of the walnuts. Another version uses macadamia nuts and Mango syrup. Another tradition is to poke a single clove into each diamond of baklava prior to cooking. However I have found this problematic with people unfamiliar with cloves mistakenly biting into them instead of removing them before eating.
