For passenger comfort I always worked with a standard 3degree profile... roughly 2500fpm... not 5000fpm LOL..
Also plan on 1000fpm the last 1000ft climb so you dont spit the boss in the ceiling and beware the throttles.. they are very sensitive to movement and with the aircraft being so overpowered, it can make the flight very uncomfortable for your passengers. Being smooth on the power takes practice in the 60.
