custom chainring for reduced chain drop?

Got a general MTB question that doesn't fit anywhere else? Here's the place.

Sorry, you've missed the boat on reasoned discussion, were into headbutting and bottling now :o

Naw, all sounds reasonable to me. I think the people who have experienced a clutch on a particular design (yourself and smoothy) are going to be the ones who can best comment on how it affects it. I myself am moving to SC/I VPP as I've loved it in the past, but won't be going clutch on that in the foreseeable future.

If clutch potentially has a negative impact on suspension, I wonder if it's more pronounced on longer travel...

I don't think it's a cae of having a negative effect on suspension, it's just a possible point of failure, if the mech's movement is being restricted too stringently.
I'm not going to a clutch mech for the foreseeable future, but it has nothing to do with any concerns - I've just got a non-clutch 9-speed XT setup fitted earlier this year, and it's got plenty of life in it yet.
Chances are that the next one I get (in a few years, since they generally last a while) will be a clutch mech.

Some of the early SC VPP has a very large amount of chain growth, one of the largest I have seen. They have reigned it in now with a redesign, but the old Bullitt was 30mm at full travel (160mm). Though not as bad as old Orange long travel bikes with the high pivot.

Well in that case I'll throw my hat into the ring, tho it is still I'm aware slightly OT. I've just fitted an XT Shadow Plus mech to my DW Link equipped Ibis Mojo SL with no issues whatsoever.

To be fair Shimano don't use the term 'clutch' their description of 'plus' reads like this:
a switch at the pulley cage to enforce a heavier spring tension and activate a friction stabilizer to counteract the forces of up and down chain momentum in rough terrain.

I had a standard xtr mech on the Blur for nearly three years and had no problems either. I did use a neoprene protector to protect from slap but lived with it. I moved to the clutch as the old mech got mashed on the downhills in Bulgaria. I thought while I was at it I would treat myself to some shiny 10 speed with a clutch to see what it's all about and I like it.

The clutch is more of a stiff joint and you can push it fully forward while engaged with one hand. As mentioned before, the force of the suspension is not going to be hindered by it in a noticeable way while riding.
