I think the advice above is sound. I've owned a vk60 and now have a vk75se. Using Watt/Puppy 6's. I've never felt like I needed more power. However, the 75se is a much better sounding amp. Much superior bass, more top end extension, better dynamics, better stage, you name it.
Since I'm not famiilar w/ your Talon's, which I assume you'll be using, I can't really answer this.
The BAT is not a whimpy 75 watt amp. It's got some serious juice in it...
