With as many variables offroad has I doubt you were seeing that big of a difference with 5C more, you may have been noticing the weight loss from running the 3800 though.
I have a trakpower 4900 and the new reedy 5000, I would recommend the reedy, plus it was about 15$ cheaper. I like the ability to run for over a half hour at a time, and can do it with these bigger packs. I've never run a smaller lipo (3200, 3800), but I'm sure they're just as punchy, just less run time.
I would recommend getting two lipos as soon as you can afford it, having one charge while you're on the track means you'll be able to run back to back with nearly no breaks, if you wanted to.
