Shorter is fine. The '02 GSX-R ones I have fitted are ~50mm shorter than the Bandit ones and I cannot rate them highly enough. The bike no longer pushes wide on hard cornering, you just pick a line and it is rock-steady all the way. No clearance issues either.
TLs and Busa's are another option. Both are a bit longer than the GSX-R's and you can also use the Bandit's brakes as they all (busa, tl and bandit) use the same set-up.
