I tend to look at it as a hobby as much as anything. Although there is rarely money to be made in selling on used bats, it has been widely proven on here that bat collections are admired. I know some will say that they are there to be used but is it a crime if people buy them because they want to possess a particular bat? The history of bats is fascinating and (possibly) some of the current bats may become collectors items in the coming years.
I say if you have a serious collection of bats it should be applauded, whether you use them or not. We are share a passion on here and I for one wish I had a wider collection - if it means that some hardly ever get used or occasionally used at a net then so be it
I currently have 3 with a Bubble pre-ordered and wish I had three times that amount! I constantly get bat envy on this site
