Brian 4 Ever

1. I have Gemini PT 2000 turntables and the club I spin at use Tech
1200's. How much of a difference are the pitches on the two
tables?Reason I ask is b/c i practice at home and i need to know when i
go to the club, what kind of adjustments i need to do.
2. What are the best needles out there for mixing, scratching ect but
dont wear down the vinyl quick...I have Trackmasters SK2 and they are
pretty decent. However whenever i try to scratch the needle sometimes
pops out of the groove even if i adjust the weights on the table.
3.Whats the best way to keep vinyl clean. Problem i have is that my
records skip alot except there arent scratches on them or anything. The
radio DJs i play alongside have noticebly older vinyl yet they dont
skip. Whats the secret?
4. When u put up the pitch +2 on a record, is that like adding 2 BPMs to
the record or is that something else??

Thankyou to anyone who can answer my Qs. Some of these have been bugging
me for a while. Thanks again
