Love it!
Your willingness to try various techniques and methods in this craft is very commendable.
Makes me want to dig out my Tamiya 1/48 Ar 196A but I have sooo many other kits I've promised myself to do first.
I must say though that stretched sprue is one technique I'll always avoid since I recall that toxic burned plastic smell from when I was a kid "slapping" some plastic models together. I didn't think it was a good idea back when I was 13 or 14 (no ventilation in the apartment in New York) and I just don't want to wear my respirator/mask with my glasses while I'm working on a model. I do think my paint booth would probably suck out most of the fumes but I'll stick to EZ Line.
