I have a 25 ft. rope on my climber,when it gets tight I stop,most of the time.a few times I will go higher if it is in an open cut.

I only use H.S. Sent-a-way spray,and dont have a problem with game smelling me.I have used 15' ladder stands with same results,when I use the spray.
don' t forget to spray everything,cloths,foot wear(sent-a-way powder),glovers,and most imporant of all your hat.

as for the hights;just think of setting in an office chair,and don' t dewell on how high you are.[&:]
