Its an attitude that began long before this thread and is getting rather tiresome and self defeating. As you have heard NEITHER deck you should not form too many judgements. Neither are you an engineer. Something can be competently designed but then improved further by an additional factor. An example might well be the sme v and optional use of the silicone damping tough. At no point have I sniped at you bub, or made silly comments like "poncy", I have restricted my remarks to the issue at hand - I am just saying there are alternatives. Go ahead and ignore it if you wish - but if you do so just solely because I have made the recommendation then you are shooting yourself in the foot.
