I think I can vouch for Dipuraja's CTM.
My longtime CTM standard was CK's. I've probably tried every single one on this site and countless others. (Not an exaggeration)
Recently I had moved to Mick/CBM's CTM, as I felt it got me closer to the CTM I remember from the UK.
Dipuraja's is very similar to CBM's, using a yogourt/patak's red masala sauce. The main difference is that Dipuraja's uses slightly less sugar and coconut, and adds almond powder.
To me, this is as close as I have ever got to BIR. I don't however rate Dipuraja's Tikka recipe. I found the finished tikka was overspiced. This may however be my doing. I cut the chicken/lamb up to finished size chunks. Perhaps the intention was to marinate larger chunks (breast into thirds?) and chop later. I did notice that Dipuraja in some of his videos seems to chop the tikka before using.
