That's probably what's needed. The last time I experimented with TMY I found that it had an upswept curve shape (similar to Acros) which was the opposite of what I wanted but I didn't pursue it very far.
The biggest difference I see between HP5+ and Delta 400 is that Delta 400 has a bit of a built-in S-shaped curve with a little more low and midrange contrast and less highlight contrast; usually straight prints can print with a hint of highlight detail that's absent with HP5+.
I find it interesting that Ilford's moving away from the "modern" straight-line curve shape that began with TMX. Although the straight-line response may be more technically "correct" I prefer the old-style look.
