New lens option

[Down to Earth]

Its been close to two years now since I bought my Canon 50D off Finnbay here and paired it with a 70-200 L series Canon lens and I've been more than happy with it, especially shooting my kids swimming events. I'm finally getting around to buying a smaller zoom lens and would like any input on Tamron and Sigma glass. Here is a link for a comparison of the two I'm looking at:

I have no idea what lens you are considering, due to silly rules, but if you go to the HSOforum for BH Photo Video and look them up, they will show users reviews. BH is also a top notch source to buy from. I have a Sigma ultrawide and it's an excellent piece of glass.
