Honestly, the answer is sometimes it's better to do it, other time, no. It really dépends on the recruits, on the expected battles coming, on challenges you see could be coming your way.
In D1, I put 20 HVS right off the bat when I want to dissuade other teams to challenge me.
If I am lurking, I put none until the other team has put his guard down...
But most of the time, I make sure to manage my money well and not spend when I do not need to.
