You probably won't need HSS to often with triggers.
In fact, as I'm learning this flash stuff, I'm starting to think HSS has rather limited use.
Was reading this today (yes it takes more than a few minutes and is the same for Canon) ....... http://www.scantips.com/lights/flashbasics2b.html

Thanks for that, it's a very good and thorough article. I didn't realise that a normal flash stops action better than hss flash... learn something every day.
