SMP Saddle/Bent nose question

Bent nose on the saddle that is.
Would like to try one of these on my mtb, but before shelling out big bucks was wondering something.
When climbing steep hills often I shift my arse to the front of the saddle in order to keep the front wheel on the ground. Since the nose of this saddle is angled down will that cause me to lose saddle height while going up these hills, or does one just never get that far up to the front of the saddle when sitting?
Any other comments good or bad re these saddles? Considering the Glider or the Lite.
