Smile RPS 7th Drive: 21 High-Weight Ks

We are starting a new drive, featuring the following 21 high-weight Ks:
Batch 1: 2235, 2265, 2295, 2325, 2355, 2415, 2445, 2505, 2547, 2565 [10 Ks]
Batch 2: 2655, 2685, 2715, 2745, 2775, 2835, 2865, 2895, 2925, 2955, 2985 [11 Ks]

The idea is to try again some high-weight Ks, and to make available candidates for small but reportable primes, good for newcomers and people with slow machines.

The test files sieved to 5T in the 350-600k interval kindly provided by Beyond.
Found primes are given in post #2 below.

We are starting at 360k, using 1k and 2k test files given below. On my 2.66GHz quad P4, one test at 365k takes about 140 sec, meaning about 52 hours to test a 2k file. [All Ks have FFT jumps to 28k in the 365-367k range.] Smaller and larger test files, and those in the 350-360k range available on request.

Update (Aug. 23, 2009): Continuing from n=600k to n=1M with 20 Ks. k=2865 stopped at n=600k and released. Sieving by Beyond, Thomas, amphoria and Kosmaj.

Update (Sep. 13, 2011): Extending the Drive past n=1M!

Happy hunting!

And I'm taking 360-362.

Beyond asked for a large file, and I sent him 370-380.
