I think if you haven't played loosehead before, it is always useful to know the correct technique for both 1 and 3 (just incase you need to switch as a substitute), so I think you should go for it.

 

If you have played loosehead before, and prefer tighthead, stay at tighthead; if your right ankle is too sore from the amount of pressure on the tight side, then you should switch to the loosehead position until its feeling better.

 

Hope this helped.
