OK, new guy on deck. I was working to exploit the Spring Attack angle, but short of cross classing into Barbarian or Scout(THAT would be a mess), it was impossible for me to get into and out of combat with my skin. I worked with my DM and another guy in my group, and we expanded on the Dash feat in the Complete Warrior and added the results into the Rogue Talents:
Dash - If you are wearing light or no armor and carrying a light load, your speed is 5 feet faster.
Improved Dash - Req. Dash - If you are wearing light or no armor and carrying a light load, your speed is 5 feet faster.
And as an advanced talent:
Greater improved Dash - Req. Improved Dash - If you are wearing light or no armor and carrying a light load, your speed is 10 feet faster.
So you spend 3 talents, get another 20ft. of movement, and don't have to lose some back stab bonus in cross class stuff.
So far, it doesn't seem unbalanced and I'm not dead> Go Me.
