Haha, yeah, I thought it would be an interesting question, and decision. For some folks, pretty easy, for others... very, very hard. I think too, some of it is a function of TIME. Many of us just love bows, and are always looking for that one magical bow, so when we can afford it, we add to the collection...
Then you have a new bow, and you spend time learning it, and tuning arrows, and your prior favourite sits on the rack. But then, months, weeks, or days later, after time has passed, you pull out that older bow you love, and compare!
Then, sometimes (as in my case!) that new bow grabs you and won't let go, and the prior favourite goes back on the rack. OR, you shoot your old favourite, and the magic hits again, and you can't put it down. Its still the ONE.
But then you think about PURPOSE, and that short bow you like for deep cover, or a tree stand. But that long, string-follow ASL of yours is SO smooth, and fun to rove with, or that light-ish recurve you love for 3D courses...
Its never easy picking just one, that for sure.
I wonder if bows are like women? Some guys have a high-school sweetheart they never stray from, forsaking all others, where as other people play the field, and weigh... options. Be interesting research
