Got one mail order, boomerang is 36-40T but bash guard is 38-40T will there be a problem running 36T chain ring with it?

Do you not mean Straitline?

I imagine it will work, just a small chance of the chain in the slightly bigger gap

Yup Straitline, ta.

I’ve got this blackspire der guide which is similar to the silent guide – no moving parts – its ruddy excellent, very light, never lost a chain on my BFe. I prefer the Taco to a bashring as its a little lighter and seems neater, and its all cheaper.

Thanks for the suggestion Toys but that’s no good for me, the top guide will hit the pivot on my Meta, has to be more swept back. I think it will be okay but won’t know for sure until it’s all on.

Plus I got it cheaper than the Blackspire. 😀
