Since we're each entitled to an opinion.... I dont beleive a HUD is 'crucial'. Sure its an added benefit and some sumps etc would almost mandate it, but thats not the case for a lot of caves.
My bog standard KISS has done many a cave dive (its what I bought it for) without a HUD, or an offboard gas supply, or a flood recoverable loop.
Whilst I'd like all 3, they can all be mitigated by a willingness to carry/stage an appropriate ammount of OC bailout.
The main driver for me going CCR cave was quite simply gas logistics. Having gone that route the benefits of bubble free diving (visibility and noise) then became very evident.

OK Zak, you're right, crucial maybe overstating the issue. After diving without one and then with, I just think they are very helpful, no need to take your eye off the ball...
Obviously one can do without a HUD. Those Wookie hole dudes didn't need no stinking HUDs.
And gas logistics are the big, glaring obvious benefit of CCRs in cave diving.
But what would you say to a reclining chair with a nuclear powered scooter built in?
