Thank you Anon. All that really is very encouraging. I will be starting to put out feelers for 3D40’s tomorrow!

Spline size – yep, it was shank size equivalence I was worrying about, always being vaguely aware that splines were going to be different. The thing is, barring the shed-find to end all shed-finds, we won’t be bothered by having to match the hubs to the SBAC 4’s of a pair of RR Peregrines.. I wish we had that problem!

Thanks again!
