Hi @banagan,
Well, you only need to vote once and the votes will stick with your account until the next time you choose to re-vote again. So basically, you spend 1 LSK for 33 choices (either vote or unvote). After spending 4 LSK to vote for your 101 delegates (one wallet can only vote for 101 max), those 101 delegates will be your votes until the next time you decide to revote.
That's actually a good strategy, vote first for liskelite and GDTpool, then maybe lisk.builders ( I added them yesterday and they have a good portfolios with a nice lottery program). Yes you can pick earnlisk to see people in the first batch or use dpostool as well.
But I suggest you to go through their proposals.... you know.. just for a better sake of the network :)!
Cheers,
PS: and the voting address is your wallet address - the wallet you use to vote for them. Just send them 0.18LSK to confirm!
