If you never lock the front hubs in on the road I say go for it!!
Locking one hub works when offroad if your having trouble either steering or taking tight corners. Mine has fw d44/9" spooled front and rear on 38's and steers no problems as far as power steering goes, 86 BII with 92 Sploder box and pump.
Locked front can make tight turning a little more challenging some times but it's well worth the locked front on the trail imo. I've had my last 5 rigs with front either welded or spooled and won't go back to open front on my wheelers ever again. Trail performance and how much easier you can climb stuff is night and day better.
Actually the Yukon mini spool I bought for the d44 was just under a hundred bucks.
No doubt a selectable would be better but when money isn't there, you gotta do what you gotta do.
If your ready to take your rig to the next level of trail ability, locked front is certainly a way to do it.
