st. Pauls suite f

So basically im playing this full suite and on the first part Jig on the third page 8 measures before 9 there is a part where it is straight triplets and extremely quick I know half position is best for this part here but im wonder at the last few triplets before the tremolo should I shift back to first position. Its on the violin 2 part.
