Getting Tamron 24-70, keep Canon 24-105?

Recently I bought a Canon 70-300L IS and am very happy with that lens(using a 6D)
Now I am planning to get the Tamron 24-70 F2.8. I also have the Canon 24-105L and I do like that lens.
However, I wonder if I should keep it after getting the Tamron?
Maybe some forum members that had similar situation can give some opinions and reasons either way(keep or sell?) and why?

The Tamron is a brilliant lense with much less wide angle distortion than the 24-105.

I would sell it, if it were me. Too much money to have sitting around for that much redundancy. Lots of other good stuff to put to use that ~$700 you would get for the 24-105

I kept mine. Every time I think about selling it I remember how handy it is as a walkaround when I am on holidays.

why dont you just keep it for a while and see if you use it or not. if it collects dust then sell it. After you get the Tamron this should be a very easy decision to figure out on your own.

The reason LJG pointed out is what I fear most when I sell it. However, as Elitejp stated the best option is to keep it around for a while and see how things progress I guess.
.....decisions, decisions....

I agree 100% with this option. I've regretted selling a lens before for simular reasons. Unless you have to sell one to afford the other it's best to hold onto the 24-105 for awhile until you feel comfortable with the decision to keep or sell the lens.
