Lee, I'm heading toward that "past the prime" region myself. Today climbing is 
not a problem, but I have to be realistic about 5 & 10 years down the hill. 
Since my whole installation will be new I'm going to use a Hazer. If you have a 
Rohn fixed tower you could add that pretty reasonably I think and solve the 
climbing issue. I'm really leaning toward the SteppIR but confess that without 
the Hazer I would have to overcome the same issues you're dealing with.
