Reserving S311 and S340 to n=300k.

210*340^104298+1 is prime! (264031 decimal digits)
76*311^135562+1 is prime! (337926 decimal digits)


Note: This makes both bases 1kers. MyDog

Reserving a bunch:
R233, R234, R236, S252, R258, S259, R275, R326, R337 to n=300k.

Well, and 35 · 326^174298 - 1 is prime (makes a 1ker for this one, too).

I suggest taking 3.7.8 for a spin. You can compare the results then choose if you want to upgrade. 3.7.8 might be much faster than 3.4.3.
