acually for you to wield two weapons at the same time you need two weapon style not two handed style.

Yeah, there are several problems I forsee that probably warrant restarting. First, you should've put the two points in two weapon style.
Second, you should never put points in bastard swords. They are the rarest weapons in the game. Much rarer than magic katanas. There are no good bastard swords easily available. If you don't use a weapon you have proficiencies in, you suffer a huge penalty to hit and to damage (larger than the manual says).

Hi,
I have a berserker character with the following weapon proficiencies:

Bastard sword ++++
Two handed weapon style ++

Now my question is which of the following combinations does most damage.

Bastard sword +1 and a normal Bastard sword
or
Bastard sword +1 and a Long sword +1

I use the first combination since specialiced in Bastard swords.

Well, long sword is speed, have 1d8, bastard 2d4, but without profice on the weapon, very dif??????

simple, just get two bastard swords +2
