Hi Rally,
Thank you for taking all that time to comment on the set-up, it is all very 
helpful.   I will go ahead and order me one.
Thank you once again.

Best

 I haven't had a chance to use them yet - they only arrived earlier
 this week !!
 
 So I don't think I am in a position to provide the recommendation you
 require, but they certainly look like they would stand up to the
 rigors of normal use.
 
 I purchased the "Long Blimp" and a normal "Blimp" - but they are
 really the same thing except the long has an extension piece (supplied
 as a separate item) that you insert in the middle  and you get an
 extra hairy cover that caters for the longer overall length (as well
 as a normal length hairy cover !)
 
 They are a copy of the Sennheiser design as best I can tell from
 pictures (without a real Sennheiser to compare it to). 
 So the design should be good enough, whether the materials are of
 equivalent construction would be difficult to tell, but its still plastic.
 
 As I look at each part for you, here are my thoughts :
 
 The Pistol grip is strong plastic and looks bullet proof. It has an
 encapsulated brass female threaded part in the base to allow the grip
 to be mounted onto a pole or tripod. 
 
 The Blimp body is made of plastic mesh covered with a very finely
 woven black liner. I would say that it would be very difficult to
 break this body section, it would just flex, I can't really ascertain
 how well the end sections are joined to it, but a bush fix (if in fact
 ever necessary) would be glue, tape or zip ties ! Each end of each
 section is reinforced by a solidly made joining section which has a
 simple sort of plastic bayonet fitting - seems OK to me.
 The end caps would be difficult to break in any conceivable normal use
 scenario. Their half dome design is very strong by its nature.
 The bayonet mechanism seems robust enough considering what it has to do.
 
 The hairy covers are lined with what looks to me to be a high quality
 open eave mesh nylon liner - its quite thick, and the two zippers look
 to me to be of good quality. The zippers allow the pistol grip to be
 positioned and protrude anywhere along their length. The hair is a
 little shorter than my Rycote - cant tell you if that is good or bad ?
 
 The clamp which adjusts the pistol grip angle seems marginally on the
 flimsy side, but strong enough I suspect, but even if it broke it
 would prevent its use.
 Its hollow behind and I think I might add a little strengthener into
 it just in case - that would be little splint of metal like a 1" nail
 and silicone it in. Possibly overkill - but its probably the only
 thing I can see so far that might need improving. Its trivial.
 The clamp operates on one side of a blackened steel shaft which goes
 through the grip and rail and ends in a plate on the other side.  
 
 The rail system seems to me to be very strong.
 In fact now that I opened it up and had a good look - I would say that
 its bullet proof unless used to fight off a jungle animal !
 
 The bottom of the rail has approx 6mm thick triangular section that
 supports the grip - seems strong enough to me. 
 
 The cam operated clamps that clamp the rail to the main body are
 average - not so much in strength but in the way they operate - one
 end felt like it clamps well and hard the other end felt like it
 clamped marginally. Haven't checked the others. 
 As a guess only - I suspect the holes the cams rotate on were hand
 drilled and their positioning is not perfect.
 Given their use, if it ever became a problem - you would simply stick
 a bit of rubber or leather in between to increase the thickness, worst
 case would be to glue them down, but really once assembled, it cant
 move anyway. The issue would be if somehow it squeaked in use, I am
 sure it could be adjusted
 
 Thats about it really 
 
 I think the only concern would be if the plastic went brittle over
 time due to UV exposure or something like that, but being black and
 being covered in black fabric and then covered with a hairy cover - I
 really doubt that could ever be a problem and if it was in 5 years
 time you could afford to replace it !
 
 I would say that this is a very hasty superficial report purely to
 respond to you in a short time frame.
 I have exaggerated the issues somewhat and my suggestions probably
 make them sound much worse than the reality.
 The web site probably has some info about the materials used in the
 construction - cant recall.
 Just looked - apperas thats it sABS plastic - so that should be tough
 enough
 I also noted they have a slightly different version that I think may
 be even stronger its listed as the "40cm Cine Blimp windshield
 windscreen" - It appears to have some metal componentry at the point
 where the grip joins the rail system.
 So that could be another option for you to consider, I am sure they
 could answer any of your questions.
 
 Overall I can say that I am very happy with the quality and extremely
 happy with the price I paid and I would also say that I am reasonably
 fussy.
 
 Hope that helps.
 
 Cheers
 
 Rally
