Like Harold said, the dropped nose is there to give you a little bit of relief when you are on the nose of the saddle for steep climbs and will have no effect on sliding forward when the sit bones are on the wings of the saddle. That said, personally, I've never been able to get along with any WTB saddle (Volt, Rocket). With the hammock shape on both, angle the nose up to prevent sliding forward, and that nose becomes very invasive, especially on steep/extended climbs. (This is exacerbated by the very flexible nature of the middle of the saddle shell.) Tip the nose down for relief, and I end up sliding forward.
I tend to gravitate towards saddles that are flat at the front with just a little upward swoop at the back. My rides are climb heavy and this style allows me to tip the nose of the saddle down 1 degree for more comfort, without sliding forward. My favorite saddle is the now discontinued Ergon SMC 3 saddle. Incidentally, I tried the more padded Ergon SMC4 Comp Gel for a short period and while comfortable for rides up to an hour, longer than that and I would sink in the saddle too much causing more pressure on the sit bones as well as the soft tissue.
If you are riding 2-3 hours per ride several times a week, you may find that a saddle with more supportive padding to be better as it won't break down on longer rides. It does take a bit of trial and error to find the Goldilocks shape and padding profiles that suit you.
