Also is DD-X (being supposedly similar to Tmax) also not ok for LF? And if so what is Ilford's equivalent.

The RS version is optimized for replenishment and is packaged differently (two solutions rather than one). The non RS version is not suitable for replenishment, and is cheaper.

While DD-X may give similar results, most likely it is chemically quite different. I don't know that there are a lot of near identical equivalents between the Kodak and Ilford product lines, other than ID-11-D76 and, formerly, Perceptol-Microdol X.

Have you reviewed the page of Ilford developers on their site: http://www.ilfordphoto.com/products/...ilm+Developers ?
