used this before and it was quite nice to do so. Carrying it about, not so
nice.
So my question is what are the relative merits of loam based and peat/peat
substitute composts?

Hi mark, wow, to answer your question would take forever but regards to your cuttings mix just sieve Irish moss peat and by volume mix 50/50 with very sharp sand
My gut feeling reference soil free v soil based compost commercially has alot to do with weight and transport plus that in most commercially made
soil less composts all sorts of materials are added to bulk it up! In practice, you would not believe how useless some composts are regarding nutrition,
depending on how long its been bagged etc. Even commercially several large growers locally that supply me with shrubs etc. have had over the last couple of seasons alot of problems with soil less composts, regarding consistancy of
nutritional content and of course when a crop fails, its very difficult to prove that the compost is at fault. The main thing about a John Innes type compost was that years ago we all mixed our own so you knew exactly what was in it.
