Wife made this for me for

About a dozen. 

I only take three to league, spare ball included.  Most of them get donated when they're discontinued or replaced.  I'd rather see them getting used than gathering dust somewhere.

We're similar.  I have 9.  4 are in the locker but I usually only take 2 out and the spare for league.  I usually take 5 (4 strike and plastic) when I go to other houses for tournaments/UBA/etc.

I also donate my older equipment to friends who look like they could use a ball.  I only have 2 balls that I am keeping around for mostly sentimental reasons (I can still throw them as they still fit though).

I have 12 and that's after adding my Tribal Fire.  However, the oldest stuff is being sold or donated by the end of the summer.  Normally 3 come out for league.

Too many is relative...the broader question is whether someone knows how they will react when compared to another since, during competition, you have to be able to make an equipment change and know what the new piece is going to do. 

I couldn't tell you just how many I have, but I have many going back into the Roto RH of the 70's (and basically stopping with the loss of our Tour in 2003).  It was mostly the Roto equipment that went on the road with me, but I also knew the relationships between the Storm, Columbia and Faball pieces in the collection for the rare occasions it went on the road (or if I got bored and wanted to do something different with league).
