If fast and easy it your goal, the electric motor gets you there..
If getting stronger, developing your legs, developing your cardio-vascular system, enjoying the physical exertion, pushing your limits and growing.. developing yourself both physically and mentally, then forget the motor. A big part of the reason I am I alive and reasonably healthy at 73 is for most of the 27 years of my adult life when I wasn't doing physical labor, I rode my bicycle to work. I didn't take it easy, I rode hard and during the summer months would often take the long way home, sometimes putting in 40 or even 50 miles on the way home from work. I sought out the steepest, most difficult climbs.. On weekends, I would go for a ride in the back country, sometimes putting in 100 miles. A few times I climbed to the top of Palomar Mountain, that ride involved over 8000 feet of vertical climbing.
When you get the top of the hill, you might not be tired but your legs haven't developed so the next time you get to the top, you aren't any stronger. When I got to the top of the hill, yes, I was tired but I would have gauged my effort based on my heart rate and I would quickly recover and be off with strength developed over the years.
The caption is joke, the photo was taken during a time trial, but I would do practice laps around the island on my way home from work.. While I was in my early 60's, I could still average nearly 25 mph for 30 minutes. Miles and miles, base miles, thousands, tens of thousands.. It's personal development, growth, and pure joy..
The comparison here is relevant. When you use goto, you do not develop your navigating skills, you're dependent on the goto. When one is star hopping, one is continually growing, developing new techniques, learning, it's like climbing the hill on the bicycle, each and every mile, you get stronger.
In your first post, you said you were confident in your goto.. Myself, I am confident in my star hopping skills, in my charts, in the images I am using. I am exercising my brain, it's not just looking in the eyepiece, it's looking in the eyepiece at exactly the right spot, pointing my averted my vision to the exact location because I know exactly where in the star field that object is.
My eyes are certainly not the best, my skills are what they are. I was never the fastest rider but I was the best rider I could be. And that's my goal as an observer, developing my skills, being the best observer I can be.
Eddy Merckx, the most successful competitive cyclist ever was once asked, for training tips. His answer:
That's my attitude when I comes to amateur astronomy..
And have fun doing it.
