So the deal is the original poster has a set space to launch in.

There won't be room to stretch his highstart out farther. There is a set amount of room, period. What happens now is fairly simple.

For any highstart to work to it's maximum in a set space, it will have to be tuned to that space. Once tuned, you'll be getting the max launch highstarts can give for that space with that highstart. If you don't want to do the tuning, then the answer to the question isn't simple. A winch setup is tuned to whatever length you lay the sucker out to. And wheter or not the winch the OP is using is going to be better than whatever highstart he's using will depend on how badly the highstart is suited to the length he's stuck with. There is a high probability that any winch will work better in his case than whatever highstart he has will be suited to the area. hmmm.... not really simple at all, is it.
