Thanks for your reply Max,
You are spot on when you suggest if I use what I have, it will require multiple modifications.
I like the Trident Teasing Rake, so that's the way I'll go I think. Also a new front roller package that they also offer, has attracted my attention too, and it's stainless steel.
