Well, Zog, I am a manly and vain person too- in a humble manner, of course. I sometimes go to heavier bows because I can. I could still shoot a 100 pound bow the last time I tried and once drew 114- and was very grateful that I did not injure myself doing such a foolish thing.
Last December I was working with a Howard Hill Tembo that I draw to about 50 pounds, and 540 grain arrows. I was doing well with it on my club's field range. One day I got into the zone with it and through 8 of 14 targets, including the 80 yard walk up, I was well above world record pace.
Then a European couple who had just moved to our university town walked by and inquired about archery in Northern California and membership in our club. We had a long and pleasant chat and then I went back to my shooting. The next target was the 50 yarder and I made three misses and a 3! Lost my mojo. Oh well, I would probably have soon lost it anyway. But it was glorious while it lasted.
I shoot a lot of different bows in the course of a year, and use different styles. I might shoot better if I stuck with just one or two, but I think I have learned a lot from all my experimenting. I do usually settle down to one bow for a major championship and I have won a good many of them.
Besides, I might win the lottery someday. Then I would surely hunt both Alaska and Africa. I wouldn't use my 42 pounder for that. In fact I usually use my 55 pounder for pheasants. I find them very hard to kill. - lbg
