some interesting points here.
For myself I'm more modeller/collector than wargamer. I was never a great model maker or painter for that matter so nowadays I mainly focus on the fast assembly sets from Plastic Soldier Company etc. They are a nice balance between "one piece" models in resin and now 3d printing.
I find hard plastic much easier to work with than soft polythene type plastic, as I find it takes glue and paint better and generally gives a stronger model.
For the Strelets kits, some negative reviews on Plastic Soldier review were offputting. However, I've made a couple of guns without much trouble.
I have a few of the ancient Atlantic sets, German Armoured cars especially, and they've always been a disappointment as the small parts tend to come off.
For Strelets, if you should decide to produce hard plastic kits in future I will definitely be interested but I would suggest good clear instructions would be a great help. My personal preference is for hard styrene and metal as again I find soft plastic is harder to make parts stick
If I find the money and the time I may get round to some more guns, but right now I'm focussing on WW2 and the Middle East so waiting for the Afrika Korps who are looking very good but sadly no word on Heavy Weapons yet?
Right now life is getting expensive and a number of things need to be done so buying and hobbies are on the back burner for a while - but just temporarily!
Well, that's my thoughts for now.
Stay safe and Carry on Collecting!
While I cannot judge all kits from the artillery series, this is my experience:
Even I was able to produce an acceptable result from A014 (Long Tom, painted as a WW1 French gun) and A015 (Schneider 105mm howitzer), so can you. I did change the wheels of the Schneider gun for more common ones, and replaced the shield which is too small IMHO, but everything went together easily, the "instruction" pictures on the boxes' back were sufficient, and the plastic can be glued with standard modelling glue. Add the excellent crew figures to that, I cannot see what's not to like.
