I totally agree. I have owned the hyped up Tower .75 and I owned the ASP XLS .91. One example: Tower .75 and APC 13-6 turned 11700 rpm, ASP XLS .91 turned the same prop 12900 rpm. Difference in weight was 1 oz.. I sold the Tower and kept the ASP (which is now sold too, but only because I had no need for it anymore)

I found that there was nothing magical about the Tower .75, it is a little less displacement than a .91 and develops less power as is to be expected. When the difference in weight is so small I`d opt for a .91 every time
