I'm looking to put together a base build for multiple lives to save on the equipment juggling and speed things up. Browsing the forums I took some ideas and came up with this:

The idea behind it (using ranger as first life to get +2 ranged dmg on future lives) is that the 6rog/6arty setup is basically the entire character, the last 8 levels just providing help in HP/BAB/feats. Will be using a GS heavy radiance repeater for the no-save blindess which should result in SA damage going off alot more.

The level progression is pretty much the way I think it should go but when it comes to the feats and enhancement choices please let me have it. All stats raises go into INT. I tried not to use many of the ranger enhancements as that class will be swapped out to others for their PL's. Stats are another meh thing... I do plan on using UMD to spam reconstruct scrolls so losing a bit of str/dex/wis to pump cha will likely happen. I chose to go WF for the immunities mostly.
