TJ front diff gear change

I'm about to change the gear ratio in my front Dana 30 to match the rear Dana 44 ratio. I haven't been able to off-road since the ratios didn't match. :( Anyway, Would y'all recommend that while the shop is doing the R & P swap, that I have them install a locker in the front? I know there is a rumor about this going right now, but I'll tend to side with Jerry B. on that issue. I don't have a locker in the rear, but I figure a locker on one axle or the other will server my purposes and since the front diff will be all apart, it seemed like the first place to start.

Thanks, Dennis
