My friend Gary Miller who is great at lighting a subject loves his Speedotrons. I think people sometimes get to wound up over the gear.
One thing that's nice to use is a amber gel on the hair like on the last photo I posted. Artificial Light outdoors is fun to experiment with.
I think the main thing is to experiment with all the light modifiers you have. Try experimenting with a Fresnel strobe or some HMI daylight balanced hot lights along with your Speedotron strobe lights for some cool effects. On the photo below I used both hot lights and strobes.
To be sure Broncolor is nice equipment. But you don't have to spend a ton of money to get great images. I think the Speedotrons are bullet proof. I have seen them dropped and survive.
Another friend of mine Ken Marcus uses a Hensel porty with a ring light quite a bit. And Dynalite packs for the other lights.
