.nastylocking out a fork barely helps climbing unless you're standing up mashing fire roads. There's a reason a lot of forks are going away from having lock switches, i.e. Grip2 damper on Fox, all the new pikes/lyriks...
Maybe Im just old school. I used to do a lot of cross country racing and having a lockout in the front really helps to send all your energy to the pedals. They probably have much better inertia/dampening wizardry nowadays though.
Its actually kind of crazy, I was really into MTB riding and racing back in 2006 and really was not involved in the sport after graduating high school. I went to a bike shop in Sedona last year with my dad to rent a bike and it was unreal how different bikes are now with the new 29 inch wheels and 1X groupsets etc. I want to check out the new 27.5 wheels, I always used to run 26 but rode my Dad's 29 a few times. The 29 have much better rolling resistance but just are not nimble enough for my riding style, especially in tight switchbacks.
