No kidding Nick!
I used silly putty on my Wheely King for the first couple months and it did work halfway decent, but in climbing, locked front and rear worked better. I bought the Maximizer lockers for mine since I could "easy" get them (they were on back order at the time, so it took a little more time ) I may go back on the front with mine since it'll now be more of a trail rig/basher since I've got the Axial as a comp-able rig. I did JB Weld the diffs on my Venom Mini-Giant and also set up one with heavy grease, which acted like the silly putty does on the smaller rigs like that and Mini-T, that one will get the putty/grease front and JB rear diffs once I get around to building it back up. Both of my rigs have steerable knuckles on the back, but I've thought about either buying or trading for the factory ARTR/RTR rear lockouts for the Axial, Not going to bother with the WK even though I don't have plans to make it rear steer either. If you're going to run any kind of 2.2 class comps with your rig it can't have rear steer on it.
One question for you Gregg, have you joined any of the forums yet? I'm on RCCrawler under the name BJoe.
