The cheliceral structures from t.montana are quite subtle, a pointed tooth rather than a blunt one, and a slight rectangular bump on the inner edge (as I'm sure you know !).
The colour is presumably at the paler end of what you would expect for t.nigrita?
I think it is t.nigrita, but my experience of tetragnatha at this level is next to nil, and I understand your reservations about photo id (not three dimensional enough) so shall I send it to you for final confirmation?
As for the e.maculipes.. this was ST3000 so inland.. but not a huge distance from the coast, sadly a lot of the hedge in the area had been flailed extensively, this specimen was from a gateway where it was still in good shape.
