shifting with out the clutch is more fun, right before i went to sell my WRX i decided it was a good time to figure out how that works

(that called power shifting ? ) a mechanic friend of mine showed on his honda before and said its not bad for it, they had to shift a tranny with out a clutch in class . (well depending on the rev range and rev matching its not overly harmful is what he told me)
when you have it rev matched well it just sucks it in, no clue how you'de start a car from a standstill with no clutch though..
