Let's look at what XI7 does vs HT:
1 point only redirected.
Which means it hurts ships in the following manner at most, how many does it lose the capacity to transfer:
CR90 -1 shield (4 to get through strongest shields) (4 with brace*)
Neb B: HA! (4 to get through strongest shields) (7 with brace)
Glad: -2 shield (5 to get through strongest shields) (9 with brace)
AFM2: -2 sheilds (6 to get through strongest shields) (11 with brace)
VSD: -2 shield (5 to get through strongest shields) (9 with brace)
ISD: -3 shield (6 to get through strongest shields) (11 with brace)
MC80: -3 shield (6 to get through strongest shields) (11 with brace)
MC30: -3 shield (5 to get through strongest shields) (5 with brace*)
Raider: HA! (3 to get through strongest shields) (5 with brace)
HTT: (Brace w/min damage to get through best shields, Brace w/redirect min to get through shields)
CR90: 3, 5 (No brace)
Neb B: 7, 7 (No redirect)
Glad: 7, 7 (3+2+1 brace)
VSD: 7, 8 (3+3+1)
AFM2: 9, 8 (4+3+1)
ISD: 9, 8 (4+3+1)
MC80: 9, 9 (4+4+1)
MC30: 4, 7 (No brace)
Raider: 5, 5 (no redirect)
Basically, HTT does a better job of nulifying Redirect than XI7 if you don't have accuracy (or in the event of ECM (autoinclude))
With Advanced Projectors, XI7 doesn't change, but HTT does on these ships (Using Redirected shields). (Note this strips the shields, number in parenthesis is vs XI7 w/Brace + Redirect)
CR90: 8 (4)
MC80: 17 (11)
MC30: 13 (5)
ISD: 14 (11)
AFM2: 14 (11)
So XI7 helps more against AP, but HTT is better in general at getting through (at least initially)
My apologies if I made any mistakes I was swapping back and forth.
