My guess is that no one has done much if any testing with the QA1 (HAL) rear shocks. You might go to one of the Grand National lists as they have been using these for a while. In general I would try them as soft as they go first. If you don't get any wheel hop on this setting it is probably the best for weight transfer.
one caution - It is very hard to evaluate individual settings without making a large # of identical passes. To start I would look at just your 60ft times and keep everything else you do in terms of burnout, staging and launch RPM the same.
Good Luck and let us know what you discover.
