Timing Belt(s) - Which one do you run?

[DSMINMN]

I only ask this as I want to save some money but I in no way want to risk the longevity of the engine I am building in school. I'd much rather spend that little bit more and more I'm covered than cheap out just to pay later. This engine is by no means going to be stock nor will the word cheap be used. Haha

I'd also like to ask the experienced about whether they've ran the OEM Kevlar and liked it or not. I ask this as it is seeming like one of the better options to go with for what I want.

Thanks for the responses guys. Feel free to keep them coming as well!
