This reminds of the story of the motorist in Ireland who stops to ask the way.. the pedestrian scratches his chin and says:-
"Ah, to be sure, if I were you I wouldn't start from here"
Seems to me you are wanting to start from the wrong place...
Forget ILF, takedowns, impregnated stuff.
Get back to basics, what is a bow for? How has mankind managed to make 'em for millenia?
How did you make a bow as a kid? Just do the same but using the skills and knowledge you have accumulated over the years... don't confuse complexity with quality or performance.
Keep it simple.
The clue is in the forum title...
If that sounds too negative, don't despair, there is plenty of time to make fancy stuff once you have mastered the basics, say a 40# 62" long simple board bow or bow from a nice clean stave.
We learn from our mistakes and a complicated design will have complicated mistakes which may be beyond your understanding.
The key thing is training your eye to see the simple even curve of a bow. Your artists eye may pick it up quickly>
Good luck.
