I recently bought a 09 WRX and just finished putting in an agency brand short throw shifter (STS). The install was more difficult than the prior two STS's I had put in (for an 02 and 05 WRX). The biggest problem I had was getting the ball of the STS into the socket. Anyway, I'm happy with the short throw but have two questions:
1) I believe I now need to get a new shift knob because the stock one won't fit on the new STS. It's very loose. Any recommendations?
2) The actual shifting of the new STS is more tedious than the stock version - like it's fighting me a bit. Definitely not as smooth as some of the other Subaru's, Honda's and Toyota's I've driven. Any recommendations?

Thanks in advance for your help.
