WorGar, you asked if the Halcyon 1/5 tongue would work. My guess is maybe. I do not have that kit, I have all the others, from ALIENS to AR, but never snagged the first guy. So, if you get a photo of it with the tongue at full length, held next to the HT mouth for me, I can tell you if it will or not and why.
I meant to mention in my complaints list, that I did trim the tail tip down with scissors, as they left a nice sharp edge to the rubber, and shaped it much more to my liking. Not perfect, like the figure at large, but more acceptable when looked at than the tip it came with, that resembles the Spear of Destiny a bit to me.
Also I trimmed off the last three of the upwards pointing spiney bits on the back top end of the headrest, making it look much better in profile also.
The shoulders of mine have no gaps.
And I forgot to mention a biggie.
The tube from the back corners of his jaw. I have seen it both ways, kinda like Sega did it, curving up and back into the head, like HT did with a seperate molded tube, AND, like NECA did it, with a longer tube curving back down and into the upper shoulder behind the shoulder domes. Not sure which is totally correct. Need Sabres or someone to confirm that bit for me, as if they go into the shoulders, I might endeavor to switch them out, and make them point down. I don't want to try that until I know for sure though.
Gripe aspect of that, the spot where they come from the jaw, is a bit too high from the corner, but we all know the jaw extends down a tad too much, so maybe the sculptor, or HT at large, wanted to maintain some visual control on the lines by doing that and raising it a small bit.
Nitpicky? sure. Bothered to death? Not really. As long as I can fix it if I need to.
And any subracted/added teeth, need to be careful. I can EASILY see that better ones can be done, but I advise against adding much gum, unless you trim away the upper lip a bit. Might make him too gummy if you aren't careful. Still, I look forward to your solution. I might follow it if I am impressed enough that it warrants it on mine.
Best of luck!
Oh, and Dedguy, sorry about the fall. I drybrushed some clear gloss acrylic on mine in places, here and there, and on the dome in places to make is shine a bit more (Mine's dome was not very shiney) and there had been a small scratch on an area, and after a hit with the clear, it can't be seen.
