Need advice for FF Lenses for A99 compared to these APS-C A77 lenses

Hi folks, I need some advice. I am picking up an A99 in a couple of weeks, and need lens advice, that is... I have two APS-C lenses for my A77 that I use a lot, one for travel only, and I would like similar focal lengths for the Full Frame A99.
These two lenses I have used with Pentax and Nikon in the past and now with the A77, either of the first two is on my camera most of the time.
What would be your best FF recommendation for the following two.

• Sigma 10-20mm F4-5.6
• Tamron 17-50mm F2.8

And the

• Tamron 18-270mm

Which I only use when my bag limit is tight with travel restrictions.  What is a good travel lens for a FF camera.

Any advice would be much appreciated.
Thanks, Phil
