I am planning on using this circuit for some AC dimming. But those triacs are kinda expensive, and I was thinking I should use a higher rated one for my project (I only need 8A per triac, but bigger is always safer). What triac do you recommend using under say $1.50 apiece and do I need to change any other components? Looking through digikey the following ones look like they have a good price for their amperage rating.

Its just gonna be used for dimming AC lights.
Here is the circuit from the first link.
Edit- Ok, I think Im gonna go with the BTA416Y-800C, 127 or the BTA416Y-800B, 127. They are both the same price, which one should I use assuming I am using that circuit without any changes?
