Hi Jeremy,
With max lag of 5, you can do both general linear tests, but with two slightly different indications.
If you want to test whether the two responses are different at any time lag, you can set your glt matrix as
00000000100000-100000
000000000100000-10000
0000000000100000-1000
00000000000100000-100
000000000000100000-10
0000000000000100000-1
If you want to test whether the two responses are different in their overall magnitude, then the glt vector would be just as you said,
00000000111111-1-1-1-1-1-1
The difference between the two tests are this: The acceptance of the null hypothesis in the first test would indicate the acceptance of the null hypothesis in the second hypothesis; On the other hand, the rejection of the null hypothesis in the second test would lead to the rejection of the null hypothesis in the first test.
