Thanks my friend @coling! I had a few (but not too many) sagging issues with the stretched sprue. I used a hairdryer to take the slack, a method that worked in this case (but does not always work). Stretched sprue is a material/method with a number of peculiarities (and, why not, disadvantages) that has nevertheless suited my style (whereas, on the other hand, I am not at all good with thin wire and the like!).
Roden kits are distinctive, for sure they do not build like Tamiya quarter scale Spits (especially the older versions! 🙂 ), but my experience so far is that they come along positively. Your skills can easily produce masterpieces out of your Roden "shelf queens!
Again, thanks a lot for the motivating words!
