I'm leaning towards the 4.46 (or even 4.27) though in case I feel like putting the 32"s back on for longer trips....the 3.73's are a no go for me.... What makes you want to go with 4.46 vs 4.27, and saying that 3.73 are a no-go for you? Im totally lost in what is best. Is more better? Or do I look like the beginner surfer sitting along side of experts, thinking….Im a dead man. LOL!!
