Needed a wallet check to advise :)
Power some up! haha, just kidding.
Ok so you have 1900 SP, a 1% vote will add around a cent on. It's enough to break the curation dust threshold, but i would go for a 3 cent vote if possible - i think that vote falls into dust for the author.
Would be interesting for you to monitor curation rewards based on your old style verses new. You can see in the chart what you described above :)
Personally I like to see someone, who perhaps doesn't have loads of time to curate, sticking bigger votes down.
I also think that upvoting mod/cm comments is a good plan (especially if they are tipped ;) )
