I ride the Murray and have done sets on the Kraz and Riot, but not blue print. Also, I'm about the same height as you but 30 lbs less for background. The murray feels kinda slick at greater speeds to me (prolly my own fault for getting a 150, I wanted to be able to ride slow to learn a lot of stuff without breaking myself lol), so 22.5-23 gets wobbly on my murray. The kraz felt way more locked in, but would scare me on landings cause it goes in the direction it lands whether you're ready for it or not. That said, I really like the murray, coming from a ronix one timebomb harf edition from around 2010. I feel like I can get away with murder on most landings, really like having such a wide base to land on, and it glides really easily, so you can take longer sets even at slow speeds - hell i've even wakesurfed it before! As for weight, its just going to depend on size, but I'll tell you the 150 isn't near as bad as I thought it would be to move around for grabs and what not, and the extra surface area gives you a ton of pop. I'll try to attach a video of me riding it in the beginning, you can see we stay around 18 mph on a 60ft line and get tons of pop without a ton of risk.
