I dont think Pink has gone out of fashion and I think its probably worth staying in your range. Remembering that with GN equipment, you will put out 4-5 models a year of different bats (Powerbow, Evo, Nitro, Ignite, Legend etc), so making just one of them pink I dont think is bad.
I think witht hings that are different (like pink), people are pretty opinionated with them and in most cases you eitehr hink they are awesome or they are terrible and in a market where there is so many bats to chose from I think thats a good thing. Because 5 people might walk into the store and say no thanks, but the other might go yes please and take it.
As opposed to that bad which is just 'ok' and your normal run of the mill bat that doesnt stand out.
Thats my consensus from wo
