Hi Animal,
When I purchased 741, the previous owner had installed bars similar to what you have described. At first, I wasn't sure if I'd like them because my hands tend to go numb, especially if elevated. After riding for a couple of years, I've grown accustomed to them with no problems. The bars look good and are at a comfortable height for me.
The previous owner also installed aftermarket Joker Machine master cylinders and turn switches, as well as braided steel hoses and cables. I doubt if the stock lines would reach.
After purchasing 901 which is basically stock, I realized that the downturn on the "apes" brings my hand position only a couple of inches above the stock height.
Have a look at the attached pictures and see what you think.
